They give you the flexibility, ease of use, and power to manipulate and change your disks in many ways that you weren't able to previously. The present version of these programs, version 3.2, are written in the C programming language. The programs are user friendly, fast, and very powerful. There are eight programs in the utilities. You can run all of the utilities from one menu, so you won't have to remember all of the commands. There is also an installation program that lets you configure the options and colors of the programs in any way you want. Professional Master Key (PMK). PMK is much more than a mere sector editor. It also edits, manipulates, renames, erases, and most importantly undeletes files. The features in PMK include: -- Access any MS-DOS disk available. Any sized floppy disk, any sized hard disk, any sized RAM disk, and any physical or virtual disk accessed through a device driver can be used. The only limitation | on a disk is that its sector size cannot exceed 4096 bytes. There is | a limit to the total size of the disk (number of clusters), but it is | probably beyond what you will encounter in everyday use. -- Access any file or sub-directory in any sub-directory on these disks. The status of a file or sub-directory is not important. PMK can easily access all Hidden, Read-Only, and System files. -- Edit all sectors on a disk. The disk is edited on a sector by sector basis, giving full access, either sequentially or randomly, to any available sector on the disk. The editing display includes both the sector number and cursor offset within the sector. -- Edit all sectors within any file or sub-directory on the disk. Files are also edited by sector, giving full access to any sector in the file or sub-directory in a sequential or random manner. -- Search sequentially for and go immediately to any ASCII text up to 70 characters long or any hex data up to 35 words long while editing a disk or file. -- Quickly display a graphical map of total disk usage and free space, as well as a map of the location of any file on the disk. -- Change any of the file attributes for any file or sub-directory on a disk. This includes Read-Only, Hidden, System and Archive status as well as the date and time of creation. The Professional Master Key Utilities, version 3.2 Page 1 Introduction to the Utilities -- Find any file or sub-directory on a disk matching an ambiguous (like *.BAT) or unambiguous (PMK.EXE) file specification, including Hidden and System files. -- Rename any file or sub-directory on a disk. -- Erase any file on a disk, including Read-Only files. -- Undelete any file or sub-directory on a disk that is able to be undeleted. Fill Disk. Fill Disk writes any message on all free sectors on a disk leaving existing files alone. It can also zero all unused sectors, removing all traces of old file data. The uses of Fill Disk are many, ranging from stamping a hard disk with your name and address (to provide you with a positive means of identifying it in the event of a theft) to merely clearing out remnants of previous work. Full Screen File Sort. File Sort rearranges the order of file names on a disk. It can sort file names according to their name, extension, date, time, or size, all in either ascending or descending order. It also allows you the flexability to rearrange the order of file names in a directory arbitrarily to suit your needs. Un Format. Protecting against accidentally formatting a hard disk is what Un Format is all about. When used regularly it protects hard disk users from losing many of their files and data after an accidental hard disk format. After a surprising format of your hard disk, Un Format, when used properly, quickly and easily restores the hard disk to the state it was in before it was formatted. The Professional Master Key Utilities, version 3.2 Page 2 Introduction to the Utilities Zero Disk. Zero Disk removes all traces of all data from a disk. Unlike Fill Disk, which can optionally zero unused sectors of a file while leaving all existing files untouched, Zero Disk completely eliminates all existing files along with everything else. If you want to make sure an old disk can't be dissected for confidential data, zero that disk. Zero File. Zero File removes all traces of a file's current data from your disk. A file deleted by MS-DOS could later be recovered on the disk using PMK. However, a file zeroed with Zero File cannot be recovered, in any way, from that disk. A file's current data is completely eliminated from your disk. By using Zero File along with Fill Disk, you can make sure that no trace of a sensitive file's data, new or old, remains anywhere on your disk. Install. There is an easy way to configure The Professional Master Key Utilities to run the way you want them to. The installation program lets you reconfigure the colors displayed. You can also change the default settings for the /Mono and /Bios options to make the utilities run better on your computer. Tiny Edit A small no-frills text editor and file viewer for use with CONFIG.SYS and AUTOEXEC.BAT files. The only strong feature of Tiny Edit is its small size. Good to include on floppy disks and for use with laptops where space is at a premium. The Professional Master Key Utilities, version 3.2 Page 3 Introduction to the Utilities System Requirements System Requirements To run, The Professional Master Key Utilities require the following "standard" equipment: a computer ............. IBM PC/XT/AT or somewhat compatible an operating system .... MS-DOS or PC-DOS 2.0 or later a monitor .............. MDA, CGA, EGA, VGA, MCGA, Hercules, Anything memory ................. 128k free (above operating system) disk drives ............ virtually anything Computer. Any computer that uses MS-DOS as an operating system and is at least compatible on a BIOS level with IBM PC computers should run The Professional Master Key Utilities without any problem. Computers that are 100% IBM PC compatible will seem to operate considerably faster due to direct screen writing for video output. Operating system. The Professional Master Key Utilities will work correctly when using MS-DOS or PC-DOS version 2.0 or later. The programs have been tested on version 2.0 through version 4.0. Additionally, The Professional Master Key Utilities have successfully run under the TopView, DESQview, and Microsoft Windows operating environments. In all cases, The Professional Master Key Utility programs run in a separate window allowing simultaneous use with other programs. PMK is not guaranteed to run successfully under any version of DR DOS. Monitor. If your computer has a monitor and a display adapter, chances are that they work fine with The Professional Master Key Utilities. If you have a color monitor and color display adapter, the screen displays are in color. If you have a monochrome monitor/adapter or a color monitor/adapter in a black and white mode, the screen displays are in monochrome. Memory. This shouldn't be much of a consideration due to the relatively inexpensive cost of RAM. However, as a minimum, The Professional Master Key Utilities require 128k of free memory above that required by the operating system. More free memory is desired, but is usually only necessary when you are using a hard disk that contains many files and sub-directories. Disk drives. Again, if your computer has and uses disk drives, chances are that they will work without any problems with The Professional Master Key Utilities. Each of the programs can work with and use virtually any MS-DOS disk your system has. This includes 160k, 180k, 320k, 360k, 720k, 1.2MB, and 1.44MB floppy drives; hard disks drives; RAM disks; and physical or virtual disk drives accessed by a device driver. Specifically works with drives controlled by OnTrak's Disk Manager and Golden Bow's formatting software What these requirements end up meaning is there is a very good probability that The Professional Master Key Utilities will run on any MS-DOS computer, yours included, with at least 128k of RAM available. The Professional Master Key Utilities, version 3.2 Page 4 Introduction to the Utilities User Requirements User Requirements To use The Professional Master Key Utilities, you are also required to have at least some of the following: experience ............... an intermediate to advanced level a desire to learn ........ and a will to discover what's new respect .................. for the power you now have Experience. The Professional Master Key Utilities programs are designed to be as easy and straightforward to use as possible. Because of that, anyone can use the utilities, a "first day beginner" or a "seasoned master." However, due to the concepts and difficulty involved with explaining the operation and physical layout of disks, some experience is desired. A desire to learn. Experience isn't always required. If you don't have a lot of experience but have a big will to learn more about what's on a disk and how it works, you have definitely come to the right place. The Professional Master Key Utilities will help you to learn more about disks every day you use any of the programs. If you have absolutely no knowledge about disks, please read a book or two that discusses them before making a plunge into the depths of your disks. Nearly any book discussing MS-DOS will help. Not only will this help you understand what is going on, but it will make you more aware of what shouldn't be altered. Respect. A healthy respect for the power you have with The Professional Master Key Utilities is likely the most important user requirement. You can be a little short on experience and low on a big desire to learn, but you must be aware that making blind modifications, especially with PMK, may render your disks useless. To give you the most flexibility, the utilities usually assume that any changes you are make are the correct ones. Experimenting with these utilities to learn more about them and your disks is fine, but please also take some precautions. Make a copy of your floppy disk or back up your hard disk before making any changes. This is important if you aren't sure that what you may be doing is what you want to do. Be cautious about modifying the boot sector, FAT sectors, and any directory, unless you are certain of your changes and their results. These user requirements aren't as stringent as the system requirements, but they are just as important. What you may lack in one requirement, you should make up for in another. The bottom line is to be careful and make sure you want what you ask for. The Professional Master Key Utilities, version 3.2 Page 5 Introduction to the Utilities Conventions Used Conventions Used To make using The Professional Master Key Utilities and this documentation clearer, here are descriptions of the notational conventions used: [ ] Square brackets. When a program option appears within square brackets that option may be omitted. An option not enclosed in square brackets may not be omitted. Do not type the brackets when specifying an option. < > Angled brackets. Words shown inside angled brackets are descriptions of an option, such as a file name or a message. An option inside angled brackets is needed unless it is also within square brackets. Again, do not type the brackets when specifying an option. When a program is running, key names are also enclosed within angled brackets to describe a key to press. An example of this exists in the main menu of PMK where, in part, the text states, "... then pressing <ENTER>." This wording, in this example, means to press the Enter key and not the letters <, E, N, T, E, R, and >. The | Esc and End keys are also referred to in this way (ie., as <Esc> and <END>). | Vertical bar. A vertical bar represents an either/or situation. One of the words surrounding a vertical bar should be typed as an option. If "ON | OFF" is shown, it means that either ON or OFF should be entered, but not both. Do not type the vertical bar when specifying an option. ^ Caret. A caret represents the control key. It is always shown preceding a key and means to hold down the control key and press the key specified. Thus, when "^Home" is shown, it means to hold down the control key and press the Home key. Within this document, the words <LEFT>, <RIGHT>, <DOWN>, and <UP> refer to the left arrow, right arrow, up arrow, and down arrow. The words or lettering that appears on a key describes every other key. The Professional Master Key Utilities, version 3.2 Page 6 Installing The Professional Master Key Utilities The installation program for The Professional Master Key Utilities changes the colors and default options for any of the programs in the utilities. For most people, installing the utilities isn't necessary if each program runs fine as it is distributed. However, you may install the utilities to better meet your liking if you don't agree with my selection of colors or need to use the /Mono or /Bios options whenever you run a program. The complete command to run the installation program is: INSTALL [/Mono ON | OFF | AUTO] [/Bios ON | OFF] Examples: INSTALL accept the current defaults for /Mono and /Bios as they exist in INSTALL.EXE and use those defaults when installing the other programs INSTALL /Mono ON display all screens in monochrome and install the other programs to display in monochrome; install using the default for /Bios INSTALL /Mono OFF /Bios ON display in colors using BIOS screen writing functions and install these settings in the other programs INSTALL /Mono AUTO /Bios OFF display all screens in color if a color display is found, writing text directly to the screen Changing Options To change one of the options in a program, type the option on the command line when running Install. /Mono (Toggle monochrome). Whenever you want all screens displayed in monochrome set the /Mono option ON. With the /Mono option ON, text is displayed in monochrome regardless of whether your display can show colors. When the /Mono option is OFF, displays are always in vibrant living color. When the /Mono option is AUTO, displays will be in color when a color display is detected or monochrome when a color display isn't found. The default setting for the /Mono option in the distribution files is AUTO. The Professional Master Key Utilities, version 3.2 Page 7 Installing The Professional Master Key Utilities /Bios (Toggle direct screen writing). Whenever you want all screen writing done using BIOS function calls, set the /Bios option ON. With the /Bios option ON, all screen writing is done using BIOS function calls. This method of display is slower, but will let computers that aren't 100% IBM compatible run the utilities. The /Bios option also may need to be ON to run the programs from within a windowing operating environment. When the /Bios option is OFF, all screen writing is done directly to the screen. The default /Bios option in the distribution files is OFF; to write directly to the screen. If your computer is not 100% IBM compatible, you may need to configure the programs to use the BIOS screen writing method. If the utilities don't seem to run on your computer, try running or installing them with the /Bios option ON. Changing Colors Modifying default color settings is fairly easy. After starting Install, highlight the menu selection, "Change default program colors," and press Enter. The utilities have six color categories, listed below. The colors for each of the categories can be changed to any available foreground and background color. The six color categories are: Window Border Color Border Text Color Informational Text Color General Text Color Cursor Color Changed Data Color Only one color category at a time can be changed. Select the category to change by pressing Enter until that category is available for modification. If you wanted to change the Cursor Color, press Enter until you see: Changing: Cursor Color Once the desired color category is selected, you can change its colors. Modify foreground colors using <UP> and <DOWN>. Change background colors using <LEFT> and <RIGHT>. The sample display of the current color category is updated to show its current colors, as they are changed. The Professional Master Key Utilities, version 3.2 Page 8 Installing The Professional Master Key Utilities | Press Esc when you have changed all the colors you can stand and want to return to the menu. Installing the Programs When the options and colors are set, install each program, one at a time, by highlighting the appropriate menu selection and pressing Enter. As each program is installed, gears will grind, steam will blow, and your disk drive will spin. In a few moments, the program selected is installed. The next time that program runs, the default options and colors are set just as you wanted. INSTALL.EXE can also be installed. After selecting Quit, if you have changed any options or colors, Install will ask you if you want to save all of the changes made. Press 'Y' and Install will be installed, like the rest of the programs. The Professional Master Key Utilities, version 3.2 Page 9 Professional Master Key Professional Master Key Professional Master Key, obviously the flagship program of The Professional Master Key Utilities, includes numerous useful disk tools bundled into one easy to use program. It's a powerful program that has many useful features. The complete command to run Professional Master Key from your MS-DOS prompt is: PMK [/Mono ON | OFF | AUTO] [/Bios ON | OFF] [d:] Examples: PMK accept current defaults for /Mono and /Bios; set the working drive to the currently logged drive PMK /Bios ON A: display using BIOS screen writing functions; set the working drive to A: PMK B: accept current defaults; set the working drive to B: /Mono (Toggle monochrome). Whenever you want all screens displayed in monochrome set the /Mono option ON. With the /Mono option ON, text is displayed in monochrome regardless of whether your display can show colors. When the /Mono option is OFF, displays are always in vibrant living color. When the /Mono option is AUTO, displays will be in color when a color display is detected or monochrome when a color display isn't found. The default setting for the /Mono option in the distribution files is AUTO. /Bios (Toggle direct screen writing). Whenever you want all screen writing done using BIOS function calls, set the /Bios option ON. With the /Bios option ON, all screen writing is done using BIOS function calls. This method of display is slower, but will let computers that aren't 100% IBM compatible run the utilities. The /Bios option also may need to be ON to run the programs from within a windowing operating environment. When the /Bios option is OFF, all screen writing is done directly to the screen. The default /Bios option in the distribution files is OFF; to write directly to the screen. The Professional Master Key Utilities, version 3.2 Page 10 Professional Master Key d: (Set current drive). Entering a drive letter from the MS-DOS prompt sets the current working drive to d:. The drive letter must be a valid drive letter for your system. If d: is not a valid drive letter or if it is omitted, PMK sets the current working drive to the currently logged drive. The Main Menu Once running, the main menu appears. The information in the main menu | includes the program name, version number, all function descriptions, | current working drive and subdirectory, and Public Brand Software's address and copyright. | Currently, there are twelve functions available from the main menu. They are: | Select Drive | Select Path | Locate File | Edit File | Information | Map Disk | Edit Disk | Edit Attributes | Rename File | Erase File | Unerase File | Quit Select one of these functions by moving the highlighted bar with <UP> and <DOWN>. Press Enter when the bar highlights the function you want to execute. An alternative, easier method of selecting a function is to | type the highlited letter of the function name (V, P, L, F, I, M, D, A, | R, E, U, or Q). The Professional Master Key Utilities, version 3.2 Page 11 Professional Master Key Selecting a file Selecting a file Since a file must be selected for six of the ten functions, choosing what file to work with is vital for using Professional Master Key well. Luckily, choosing a file is very easy and almost doesn't need description. What is a file and a sub-directory? Before beginning, the definition of how the word "file" is used in this document needs explanation to avoid any confusion. A file, as defined and viewed by Professional Master Key and MS-DOS, is a name and all data associated with that name. This is just as you would expect and have been expecting it to be all along. A sub-directory is essentially just a file. This may seem confusing since we typically view and treat a sub-directory very differently from a file. However, because of the way MS-DOS creates, accesses, and uses them, sub-directories should also be viewed logically as special files. To give you more power to manipulate your disks, PMK processes sub-directories as it would files. Functions using files treat files and sub-directories equally. All functions working with files can be used to manipulate sub-directories within Professional Master Key with equal ease, with a few exceptions discussed later. Whenever the word "file" appears within this document, it refers equally to a sub-directory. The opposite is not true however. The word "sub-directory" does not likewise refer to a file. Selecting a directory Once a function requiring a file is selected, PMK checks to see if the current working drive's directory is in memory. If the directory isn't in memory, PMK now reads the working drive's complete directory structure. As it is working, the following message is displayed: Reading directory information... Reading a drive's directory may take a little time, all depending on how many files and sub-directories are on the drive and how quickly the drive operates. The Professional Master Key Utilities, version 3.2 Page 12 Professional Master Key Selecting a file After the entire directory is in memory, it is displayed. Use <UP>, <DOWN>, PgUp, PgDn, Home, and End to move the highlighted cursor to select a sub-directory. <UP> and <DOWN> move the highlighted bar to the previous and next sub-directory. PgUp and PgDn move the bar up and down to the previous screen and next screen of sub-directories. Home and End move the highlighted bar to the first and last sub-directory available. Press Enter to accept the highlighted sub-directory or press Esc to return to the main menu. If your disk doesn't have any sub-directories, selecting a sub-directory is skipped. Selecting a file After selecting a sub-directory, PMK again checks to see if files in that sub-directory are currently in memory. If they aren't, PMK will access the disk, showing the message: Reading file information... Select the file to work with in a similar manner, using <UP>, <DOWN>, PgUp, PgDn, Home, and End. The Professional Master Key Utilities, version 3.2 Page 13 Professional Master Key Edit Attributes Edit Attributes The Edit Attributes function changes the attributes, date, and time for any file on the current working drive. You can change a file's hidden, read-only, or system attributes with equal ease. A file's date and time of creation can be changed as well with very little effort. Select the initial file to work with once within the Edit Attributes function. Changing an attribute To change one of the file's attributes (Read Only, Hidden, System, or Archive), move the highlighted bar with <DOWN> and <UP>. Press Enter to toggle the highlighted attribute on or off. When an attribute is on, it is set or in an active state. Changing the date or time Changing the time or date differs from changing an attribute. Once the date or time field is highlighted, press any key to tell PMK you want to change the contents of that field. Upon pressing any key (when the date or time field is highlighted), a cursor appears within the highlighted bar. Type in the new date or time (only valid numbers are accepted). Move the cursor to a different location using <LEFT> and <RIGHT>. <UP>, <DOWN>, or Enter ends your changes to the date or time. Saving any changes Press End to save changes made to a file's attributes, date, or time. If the attributes aren't saved, the columns, "Current File Attributes" and "Altered File Attributes," show different values. Upon pressing End, they are identical. | When finished changing attributes, pressing Esc returns you to the main menu. Selecting a new file When not actually editing the date or time fields, pressing <LEFT> or <RIGHT> to change the file you are working with to the previous or next file in the directory. If a new file is selected in this manner (using <LEFT> or <RIGHT>), any changes made to the previous file are NOT automatically saved. The Professional Master Key Utilities, version 3.2 Page 14 Professional Master Key Select Drive and Path | Select Drives and Paths | The Select Drive and Select Path functions have two major designs. The | first and most obvious is it switches the current working drive to any other | available drive. The second less obvious function is that it also clears | file and directory information PMK has saved about the current drive, making | it start over from scratch the next time a file is accessed. Changing to another drive Whenever you need to work with a disk other than the current working | drive, select Select Drive and switch the current working drive. | Pressing Enter with Select Drive highlighted opens a window showing: There are 7 logical drives from A: to G: available. Enter a letter from A to G to change the current drive to any of the available drives. | Press <Esc> to keep the current drive and information. To change the current working drive, do as it says and type a letter in the range shown. In this example, you could type any of the letters in the range A to G. The "G" in this example will be the highest lettered drive on your system. | If you selected Select Drive by mistake, exit the function by pressing | Esc. Doing so keeps PMK from clearing all recorded file and directory information about the current drive. Changing floppy disks | Whenever you change floppy disks in a floppy disk drive, use Select Drive to tell PMK to clear all recorded file and directory information on the old disk. Change the current working drive back to the same floppy disk | drive once the new disk is in place. If you forget to select Select | Drive after switching floppy disks, PMK will still think the old floppy disk is present. When this happens, PMK may not work properly in any of the file functions. | Selecting a Path | The Select Path function works similarly to Select Drive. Highlight the | required subdirectory from the tree chart shown to make it the active | subdirectory. The Professional Master Key Utilities, version 3.2 Page 15 Professional Master Key Edit Disk Edit Disk The Edit Disk function lets you see and change what really is stored on your disks, on a sector by sector basis. Sectors can be accessed either sequentially or randomly. The disk can also be searched for text. After selecting Edit Disk, PMK reads and displays the first sector on the working drive. The sector is shown in both ASCII and hex codes in the 24 character wide format. Once editing the disk, a variety of function keys, arrow keys, movement keys, and other keys become effective. These keys and their functions are described in a section below. Getting help F1 (display help). Whenever editing the disk, Function key F1 opens a window showing a summary for each of the function keys. This summary won't take the place of the descriptions that follow. Instead, it will merely state what each function key accomplishes. Display formats Del (Toggle 16/24 wide display format). Since version 2.0 of Professional Master Key, two display formats have been available for editing your disks, each better suited for different tasks. Pressing the Del key switches between these two display formats. The current display format, 24 wide or 16 wide, is shown at the bottom of the screen. The default display format is 24 bytes wide. Each row shown contains 24 bytes. Most sector editing is best done using this format because it displays a complete 512 byte sector on the screen. An alternate display format, better suited for raw directory editing is selected by pressing Del. This format, 16 bytes wide, makes directory editing much easier since each directory entry (32 bytes) is seen in exactly two rows. A disadvantage to this format is that it only displays 256 bytes on the screen. Ins (Toggle ASCII format). In addition to the two display formats, there are also two ASCII formats. The Ins key switches between them. The current ASCII format, Standard or Extended, is shown at the bottom of the screen. The default ASCII format is to show only standard ASCII characters. In this format, all bytes in the sector having a value less than 20 hex or greater than 7E hex are represented on the ASCII side of the display by a period ("."). The Professional Master Key Utilities, version 3.2 Page 16 Professional Master Key Edit Disk In the other mode, toggled with Ins, all ASCII characters, both standard and extended are displayed. Moving around the disk | PgDn (Advance a sector). The PgDn key changes the current sector to the next available sector on the disk. If already at the last sector, | PgDn wraps around to the first sector on the disk. When the sector being edited is too large to fit on one screen in the | current display format, PgDn responds in a slightly different manner. | In this situation, PgDn displays the next part of the sector for editing. When editing the last part of the sector, PgUp changes the sector as stated above. | PgUp (Back up a sector). The PgUp key changes the current sector to the | previous sector. When at the first sector, PgUp wraps around to the last sector on the disk. If the sector being edited is too large to fit on one screen in the | current display format, PgUp displays the previous part of that | sector for editing. If editing the first part of a sector, the PgUp key changes the sector as stated above. F3 (Go to any sector randomly). Function key F3 lets you go to any available sector randomly. After pressing F3, a window opens showing the valid range for sector numbers. Enter a number in the range shown, or press Esc to exit that function and remain at the current sector. F4 (Go to a previous sector). Function key F4 gets and displays the previous sector edited. PMK keeps track of the last five sectors that were displayed. After moving to another sector, pressing F4 repeatedly will bring you back to one of those five sectors. F7 (Go to start of disk). Function key F7 changes the current sector being edited to the first sector on the disk, sector 0. F8 (Go to end of disk). Function key F8 changes the current sector being edited to the last available sector on the disk. The Professional Master Key Utilities, version 3.2 Page 17 Professional Master Key Edit Disk Editing a sector Making a change within a sector is easy. Just go to the desired sector, place the cursor on the desired byte, and type away. The cursor advances automatically as changes are made. Any changes are highlighted on the screen. All ASCII characters can be entered while the cursor is on the ASCII half of the display. Only valid hex characters (0 to 9 and A through F) can be entered while the cursor is on the hex side of the display. F2 (Toggle Hex/ASCII cursor). Function key F2 moves the blinking cursor from the hex or ASCII half of the display, to the other. The cursor stays at the same location within the sector that it was at, but goes over to the other side for different editing. <UP> (Move cursor up). The up arrow moves the cursor up one row within the display. When at the first row, <UP> wraps the cursor around to the last row in the display. <DOWN> (Move cursor down). The down arrow moves the cursor down one row within the display. If at the last row, <DOWN> wraps the cursor around to the first row. <RIGHT> (Move cursor right). The right arrow key moves the cursor to the right. When at the last byte in a row, <RIGHT> moves the cursor to the first byte in the next row. <LEFT> (Move cursor left). The left arrow moves the cursor to the left. When the cursor is at the first byte, <LEFT> moves the cursor to the last byte in the previous row. Saving or discarding changes Any changes made to a sector in the display must be saved to be made permanent on the disk. If a sector hasn't been written to the disk, it still shows highlighted bytes. PMK won't let you accidentally lose changes made to a sector. If you accidentally press a function key or forget to save a sector's changes before moving to another sector, PMK will ask if you'd like to save your work first. ^Home and Home (Reread current sector). The Home key forces PMK to reread the current sector from disk. ^Home does the same thing but discards any changes without first asking to save them. The Professional Master Key Utilities, version 3.2 Page 18 Professional Master Key Disk Edit This function key is used mainly to get a fresh copy of a sector into memory after making unwanted changes to a sector. After pressing Home, PMK discards any changes made and displays a copy of the current sector. ^End and End (Write current sector). The End key saves the changes made to the sector being displayed. ^End does the same, but saves your changes without asking for confirmation. Searching for text F5 (Search for ASCII text). Function key F5 lets you search for ASCII text anywhere on the disk. Enter any text up to 70 characters long to search for. The case of the string entered doesn't matter. PMK looks for both upper and lower case text at the same time. Press | Esc to skip searching for any text. All searching starts from the current cursor position within the displayed sector and goes forward until the text is found or the end of the disk. The text search can be stopped at any time by | pressing Esc. F6 (Search for Hex data). Function key F6 lets you search for hex data anywhere on the disk. After pressing F6, a window opens so you can enter any hex data up to 35 words (byte pairs) long. All hex data searches are exact. No case conversion is done on those bytes which may be ASCII characters. Hex data should be always entered in words and not by single bytes. Should the second byte in the last word entered be left out, it is assumed to be 0 (zero). For example, to search for the bytes CD and 21, enter "CD21." When "CD2" is accidentally entered, the bytes, CD and 20 are searched for. Miscellaneous F9 (Display disk information). Function key F9 opens a window showing technical information on the current drive. This display is the same as that shown by the Information function. | Esc (Return to the main menu). Function key Esc stops editing and returns you to the main menu. The Professional Master Key Utilities, version 3.2 Page 19 Professional Master Key Erase File Erase File The Erase File function is used to erase any file on the working drive. Any file can be erased by this function, including Read-Only, Hidden, and System files. A file's attributes don't matter, however, Professional Master Key currently won't allow sub-directories to be erased. Upon selecting Erase File, choose the sub-directory to get files from | then the initial file to erase. Press Esc to exit to the main menu. After choosing a file, a window opens displaying: The file, "OLD-FILE.NAM" will be erased. Press "Y" to erase the file. | Press <Esc> to return to the main menu. If "Y" is now pressed, the file, "OLD-FILE.NAM" will be erased from the | disk. If "S" is pressed, the file will not be erased. Pressing Esc, as always, returns you to the main menu. After Professional Master Key finishes erasing a file, it returns you to the file selection screen to select another file to erase. This repeats until there are no files left in the sub-directory or you eventually | press Esc. The Professional Master Key Utilities, version 3.2 Page 20 Professional Master Key Edit File Edit File The Edit File function is related to the Disk Edit function. Its main difference is that Edit File lets you see and change only what is in a file and not the entire disk. After selecting Edit File, choose the sub-directory to get files from | and then get the initial file to edit. Press Esc to return to the main menu. Once a file is selected, the first sector in the file is shown and is displayed in the 24 character wide format. All function keys, arrow keys, movement keys, and other keys act similarly as they did in the Disk Edit function. The only function keys that function slightly differently are those in the sections, "Moving around the disk" and "Searching for text." Each key in these sections work as stated in the Disk Edit function with the exception that it changes the current sector displayed to another sector within the file, not a sector anywhere on the disk. These keys are: | F1 (Help) F3 (Go to any sector randomly). | F4 (Go to a previous sector) F5 (Search for ASCII text). F6 (Search for Hex data). F7 (Go to start of file). F8 (Go to end of file). | Tab (Toggle hex/ASCII display). PgUp (Advance a sector). PgDn (Back up a sector). Also, the relative sector number being edited is displayed, not the actual sector number on the disk. The first relative sector number for a file is sector 1, no matter where the start of the file physically is. | Like Disk Edit, pressing Esc returns you to the main menu. The Professional Master Key Utilities, version 3.2 Page 21 Professional Master Key Information Information MS-DOS hides most information it has available on its disks. Pressing Enter while Information is highlighted shows much of what MS-DOS is hiding along with some other details that are both useful and good to know. Upon selecting Information, a window opens displaying the following data. The numbers shown differ depending on the format and size of the disk being used. This example shows a standard, newly formatted 360K floppy disk. Information On Drive A: Disk capacity information... 360 Kilobytes total disk capacity possible 354 Kilobytes disk capacity available (100% free). Disk logical dimensions... 512 Bytes in each sector. 719 Sectors existing on the entire disk. 708 Data Sectors possible for file usage on the disk. 2 Data Sectors exist in each Data Cluster. 354 Data Clusters possible for file usage on the disk. 1 Reserved Sector(s) at the beginning of the disk. 2 FAT copies available, each using 2 sectors. 112 Files allowed in the Root Directory. Start of all FAT sectors: sector 1 Start of the Root Directory: sector 5 Start of all Data Sectors: sector 12 Press any key to return to the main menu. The Professional Master Key Utilities, version 3.2 Page 22 Professional Master Key Locate Files Locate Files Locate Files finds and displays all files on the working drive matching any file specification. Locate Files helps users of hard and floppy disks to find several copies of a file in different places on one disk, to find the location of an individual file, or just to see all files on a disk easily. When Locate Files is chosen, a window opens displaying a few lines of help and the following prompt: Filename: * .* Enter the file(s) to search for. The wildcards ? and * can be used as | they would be with MS-DOS, as wildcards in the name to match. Press Esc to return to the main menu without locating any files. <LEFT> and <RIGHT> move the cursor to a specific location in the name to make changes. Tab moves the cursor from the filename to the extension part of the name and vice versa. Press Enter when the file specification has been entered. After pressing Enter, PMK lists all files matching the file specification given (reading sub-directories as it searches). At the end of every screen full of files it pauses waiting for any key to be pressed. | When paused, press Esc to stop the display and return to the main menu or any other key to continue listing matching files. The Professional Master Key Utilities, version 3.2 Page 23 Professional Master Key Map Disk/Files Map Disk/Files The Map Disk/Files function quickly shows a graphical map of the total disk usage and free space for the working disk. It can later display, in the same graphical format, where a file is located on the working disk and can give a visual indication of the file's fragmentation. Mapping an entire disk After selecting Map Disk/Files, Professional Master Key works at creating the graphical map of total disk usage for the working disk. On hard and floppy disks alike, this happens relatively quickly. Along with the graphical map, the amount of free disk space (in percent of total disk capacity), and the number of clusters represented by each symbol is displayed. When mapping lower capacity disks, such as floppy disks and RAM disks, each symbol in the map represents one cluster. However, due to the limited space on the screen each cluster cannot be shown for disks with very many clusters, such as hard disks. For disks that have more than 500 clusters, each symbol stands for several clusters. On my hard disk, each symbol represents twenty clusters. Hard disk users should not be alarmed if this map shows several areas containing bad clusters. This is normal on hard disks. Mapping individual files After the disk map is shown, press Enter to map file usage. Any other key returns you to the main menu. Select a directory and initial file as described earlier. Once the | initial file is selected, <Up> and <Down> changes the file being | mapped to the previous and next file in the current directory. Along with the graphical map, the amount of free disk space (in percent of total disk capacity), information on the file mapped, and the number of cluster represented by each symbol is displayed. While mapping files, you normally shouldn't see any bad clusters displayed. | Press Esc to return to the main menu. The Professional Master Key Utilities, version 3.2 Page 24 Professional Master Key Quit Quit Selecting Quit from the main menu ends the execution of Professional Master Key and returns you to MS-DOS (or other operating environment, if applicable). It returns to the same drive and directory that you started in, unless of course you switched the disk that you started from. Upon ending PMK, a window opens on the screen showing the following message: | Professional Master Key is a copyrighted, shareware product.

The Professional Master Key Utilities, version 3.2 Page 25 Professional Master Key Rename Files Rename Files The Rename Files function is used to rename any file on the working drive. Any file can be renamed by this function, including Hidden and System files. A file's attributes aren't important. After selecting Rename Files, choose the sub-directory to get files from | and a file to rename. Press Esc if you want to return to the main menu. After choosing a file a window opens asking you to enter a new name for the file. If you are trying to rename the file, "OLD-FILE.NAM," the window would show, along with a few lines of information, the prompt: Filename: OLD-FILE.NAM Type in the new name for the file. Type the new name in exactly as you want to see it appear in the directory. If leading or embedded spaces are left in the filename or extension part of the name (as an example, "Letter 1.txt"), MS-DOS will have a difficult time accessing the file. The file can still be used and accessed in a few instances from MS-DOS (and always from PMK), but a little imagination is involved to do so. [Leaving embedded spaces in the name is permitted in Professional Master Key only because you might want to make a file harder to access. Embedding spaces in a name is definitely one way to make a file harder to access from MS-DOS.] The <LEFT> and <RIGHT> keys move the cursor to any position in the old | name. A period moves the cursor from the name to the extension part of the name and vice versa. When the name is changed to what you want, press Enter and you will see: The file, "OLD-FILE.NAM" will be renamed to "NEW-FILE.NAM" Press "Y" to rename the file. Press "R" to re-enter the new file name. | Press <Esc> to exit to the main menu. Press "Y" now to change the old file name to the new name you typed in. Pressing "R" will show you the "Filename:" prompt shown above, letting you try to change the name once more. | Pressing Esc, as usual, returns you to the main menu. The Professional Master Key Utilities, version 3.2 Page 26 Professional Master Key Undelete Files Undelete Files Well, you've slipped and erased a file by mistake. It's an important file. Before using Professional Master Key, you would have to try to re-create the file if that was possible. Now, you have the ability to recover the file with a minimum of effort and continue on as normal by using the Undelete Files function. What happens to a file as it is erased? A file that gets erased or deleted actually isn't actually wiped from the face of the disk. All of its data is left intact on the disk. All that gets changed is the FAT and the file's directory entry. The FAT is updated to mark all clusters that used to belong to the file as free clusters. MS-DOS keeps track of the free clusters in the FAT to determine how much free space remains on a disk. Until another file is actually written over the clusters that used to be allocated to the deleted file, all of its old data remains on the disk. The file's directory entry is also altered, but in a minor way. The first character in a file's name is changed to the hex character E5, the Greek character sigma. This identifies that directory entry as deleted from that point onward. How can a file be Undeleted? Because a file's data is still intact, all that needs to be done to Undelete it is to rebuild its FAT chain and correct its file entry. Fixing the file name is trivial, but restoring the FAT is not. The FAT isn't designed to be complex. It works on very simple concepts, but simple to computers. It would become very tedious very quickly to you or I if we had to rebuild a file's FAT chain manually. Although the file's FAT chain cannot be rebuilt with 100% certainty, PMK simplifies the process by automatically taking its best guess about where everything should go. This may not fully recover a file all of the time, but it is most often the best method for Undeleting a file. What about sub-directories? Professional Master Key, unlike several other programs that claim to Undelete files, can Undelete sub-directories as well. The Professional Master Key Utilities, version 3.2 Page 27 Professional Master Key Undelete Files There is a limitation to doing this however. Because sub-directories do not have a size stored as part of its information, PMK has no way of knowing how many clusters it used to occupy. Whenever a sub-directory is undeleted, only its first cluster is Undeleted. Any subsequent clusters, if they existed, will be forever lost. What affects Undeleting a file? Successfully Undeleting a file depends on a lot of factors and a lot of things working right. It is not guaranteed to be always successful. Two factors, described below, can help or hinder Undeleting a file. Time. Normally, trying to Undelete a file immediately after deleting it will work without a problem. All of its data will still be intact on the disk and nothing may have been written over parts of that data. The chances of being successful in Undeleting a file go down dramatically with the passage of time since its deletion. If nothing is written to the disk since the file was deleted, there is still a very good chance that it can be Undeleted. However, if some time has passed and several files were saved, it may be highly unlikely that an deleted file can be fully recovered. Fragmentation. The chances for a successful Undeletion are also increased if both the file and disk weren't in a fragmented state before the file was deleted. Fragmented files are much more difficult to Undelete successfully. A file's clusters are normally written consecutively on a disk when possible. If that isn't possible, its clusters are put elsewhere on the disk. When a file's clusters aren't stored consecutively, it is fragmented. Fragmentation typically happens in large files that get updated often, like databases. Prevent excessive fragmentation on your disks when this is possible. Unfragment your entire disk (especially hard disks!) on a regular basis with any of the many commercial or public domain programs that claim to unfragment or optimize disks. Undeleting a file After selecting Undelete Files, choose the sub-directory to get deleted | files from then the initial file to undelete. Press Esc if you want to return to the main menu. The Professional Master Key Utilities, version 3.2 Page 28 Professional Master Key Undelete Files After selecting a deleted file, the screen clears and you will see something similar to what is shown below: Enter the first letter for "eLD-FILE.NAM" to begin undeleting it. Once the first letter in the file name is entered, the following messages appear: The file, "OLD-FILE.NAM" will be undeleted. Press "Y" to undelete the file. | Press <Esc> to exit to the main menu. If "Y" is pressed, PMK will attempt to Undelete the file OLD-FILE.NAM. After Professional Master Key finishes Undeleting a file, it returns you to the file selection screen for the chance to select another file to Undelete. This repeats until no deleted files are left in the | sub-directory or you eventually press Esc. | Pressing Esc always returns you to the main menu. The file is Undeleted, is it ok? If Professional Master Key is successful in Undeleting a file, all still may not be well. The data it has saved may not be what was originally in your file. Please check your file (use the File Edit function) to make sure that it contains the correct data. Be especially careful if the file you Undeleted is a .COM or .EXE file. The Professional Master Key Utilities, version 3.2 Page 29 Full Screen File Sort Full Screen File Sort Full Screen File Sort rearranges the order of file names on a disk. It can sort file names according to their name, extension, date, time, or size, all in either ascending or descending order. It also allows you the flexability to rearrange the order of file names in a directory arbitrarily to suit your needs. The complete invocation for File Sort is: FS [/Mono ON | OFF | AUTO] [/Bios ON | OFF] [/Sub] [/Pack] [<directory>] [/NnEeDdTtSs] Examples: FS /st sorts all files names in the current directory by file size (smallest first), then time of creation FS C:\Analysis /Sub sort C:\Analysis and all of its sub-directories using the default sort order, alphabetically by name and extension FS A:\ /Sub /Pack sort all directories on drive A: and remove erased files after sorting FS C:\Utility sort C:\Utility using the full screen, interactive display /Mono (Toggle monochrome). Whenever you want all screens displayed in monochrome set the /Mono option ON. With the /Mono option ON, text is displayed in monochrome regardless of whether your display can show colors. When the /Mono option is OFF, displays are always in vibrant living color. When the /Mono option is AUTO, displays will be in color when a color display is detected or monochrome when a color display isn't found. The default setting for the /Mono option in the distribution files is AUTO. /Bios (Toggle direct screen writing). Whenever you want all screen writing done using BIOS function calls, set the /Bios option ON. With the /Bios option ON, all screen writing is done using BIOS function calls. This method of display is slower, but will let computers that aren't 100% IBM compatible run the utilities. The /Bios option also may need to be ON to run the programs from within a windowing operating environment. The Professional Master Key Utilities, version 3.2 Page 30 Full Screen File Sort When the /Bios option is OFF, all screen writing is done directly to the screen. The default /Bios option in the distribution files is OFF; to write directly to the screen. /Sub (Sort sub-directories). Normally, File Sort only sorts the file names in the specified directory. If you want to sort the specified directory and all of its subordinate directories, use the /Sub option. /Pack (Pack files after sorting). When a file is erased, most of its name still exists in the directory. If you'd like to pack the directory and remove old, erased file names, use the /Pack option. The consequence of using this option is that erased files can't be recovered. You may want to use the /Pack option as a security option to make sure erased files aren't restored. Once /Pack is used, PMK cannot recover the erased file. In fact, PMK won't even know a file has been erased. <directory> This is the name of the directory to sort. If a directory name isn't supplied, File Sort sorts the file names in the current directory. /NnEeDdTtSs (Define sorting order). File names can be sorted on their name, extension, date, time, or size, in either ascending or descending order with this option. Any combination can be specified. Thus, if you wanted to sort by file size, then by name, then by date, use /snd. When one of the sorting option letters is capitalized, that field is sorted in descending order (largest first). When a sorting option letter is in lower case, that field is sorted in ascending order. Full Screen File Sort If you started File Sort without supplying either the /Sub or any of the /NnEeDdTtSs options, a full screen display of the selected directory is shown allowing selective sorting. The full screen display can be used to interactively view the sorting process and arbitrarily place the location of a file anywhere in the directory. While viewing the full screen display, press the keys that define the sorting order, as described above. Remember, when the key is capitalized, that field is sorted in a descending order. The Professional Master Key Utilities, version 3.2 Page 31 Full Screen File Sort N and n Sort the directory by file Name E and e Sort the directory by file Extension D and d Sort the directory by file Date T and t Sort the directory by file Time S and s Sort the directory by file Size Should you want to place a file in a specific point in its directory, you can do that also. Move the highlighted cursor with <Up>, <Down>, PgUp, PgDn, Home, and End, and press Enter when the required file is highlighted. Move that file to its new location and press Enter again to leave it there. After sorting files using the full screen display, be sure to make the changes permanant by writing them back to disk. Until written back to disk, nothing on the disk is altered. Write the files back by pressing W. | If you'd like to exit the program without making any changes, press Esc at any time. The Professional Master Key Utilities, version 3.2 Page 32 Fill Disk Fill Disk Fill Disk writes any message of your choice on all of the free sectors on any disk leaving existing files untouched. It can also zero unused sectors, removing all traces of old file data, while leaving existing files alone. The complete invocation for Fill Disk is: FD [/Mono ON | OFF | AUTO] [/Bios ON | OFF] [/Zero] [d:] [<message>] Examples: FD fills all free sectors on the default disk drive after letting you type in your message FD D: This is my computer fills drive D:'s free sectors with the message, "This is my computer" FD /Zero A: zeroes out all free sectors on drive A: FD /Zero A: This is my computer does the same thing, any message is ignored with the /Zero option /Mono (Toggle monochrome). Whenever you want all screens displayed in monochrome set the /Mono option ON. With the /Mono option ON, text is displayed in monochrome regardless of whether your display can show colors. When the /Mono option is OFF, displays are always in vibrant living color. When the /Mono option is AUTO, displays will be in color when a color display is detected or monochrome when a color display isn't found. The default setting for the /Mono option in the distribution files is AUTO. /Bios (Toggle direct screen writing).

The default /Bios option in the distribution files is OFF; to write directly to the screen. The Professional Master Key Utilities, version 3.2 Page 33 Fill Disk /Zero (zero out free sectors). If you want to zero all free sectors instead of leaving a message, use the /Zero option. When this is specified, Fill Disk clears out deleted file data with the hex character 00 while leaving existing files intact. Any message entered before or after the /Zero option is ignored. d: (drive to fill). This is the drive you want to fill. If omitted, the default drive is filled with the specified message. The drive letter, when given, must be valid on your system. <message>. Any message to write on all free sectors can be entered from the command line. If omitted, Fill Disk asks you for the message prior to running. As Fill Disk runs, it shows an approximate percent of the free sectors | filled. It can be stopped at any time by pressing Esc, which returns you to the MS-DOS prompt. The Professional Master Key Utilities, version 3.2 Page 34 Un Format Un Format Un Format does what may seem impossible, it protects you against accidental hard disk formats. When used on a regular basis, it can actually restore a hard disk to its previous state after accidentally formatting it. The complete invocation for Un Format is: UF [/Mono ON | OFF | AUTO] [/Bios ON | OFF] [/Save] d: Examples: UF nothing happens, a drive specification must be provided UF /Save C: save drive C: in the file, "B:\UNFORMAT.PMK" UF C: restore drive C: from the file, "B:\UNFORMAT.PMK" after an accidental format /Mono (Toggle monochrome). Whenever you want all screens displayed in monochrome set the /Mono option ON. With the /Mono option ON, text is displayed in monochrome regardless of whether your display can show colors. When the /Mono option is OFF, displays are always in vibrant living color. When the /Mono option is AUTO, displays will be in color when a color display is detected or monochrome when a color display isn't found. The default setting for the /Mono option in the distribution files is AUTO. /Bios (Toggle direct screen writing).

The default /Bios option in the distribution files is OFF; to write directly to the screen. /Save (save the disk). The /Save option is used to protect a hard disk against an accidental format. All necessary information is written in the file, "B:\UNFORMAT.PMK." The Professional Master Key Utilities, version 3.2 Page 35 Un Format d: (drive to save/recover). This is the drive you want to protect or recover. A drive must be specified on the command line. The drive letter should be a valid drive on your system. What happens to a disk as it is formatted? Floppy disks. A floppy disk, when formatted, loses all data that was on it. When MS-DOS's format program formats a floppy disk, every track on the disk is initialized and checked for errors. The initialization process basically recreates every track on the disk, eliminating what was there before. Hard disks. When a hard disk is formatted with most versions of MS-DOS's format program, its data is not destroyed. The only areas that are modified are the boot sector, FAT, and root directory. The MS-DOS format program mainly does two things on a hard disk: it checks for bad sectors and it initializes the boot sector, FAT and root directory. It does not physically format the disk, but just checks the state of the disk's format. How can a hard disk be Un Formatted? Since no file data is actually modified when a hard disk is formatted by MS-DOS, all that needs to be done to recover a hard disk from a format is to rewrite the boot sector, FAT, and root directory. This is possible only if those areas of the disk have been previously saved somewhere. That is really all Un Format does. One part of it saves the boot sector, FAT, and root directory. Another part writes all of those sectors back to the disk. Un Format can only recover from formatting programs that don't physically overwrite all of a hard disk's sectors. Most versions of MS-DOS's format program don't do this. One exception exists with all versions up to 3.2 of AT&T and Compaq DOS. The format program supplied with these versions of MS-DOS overwrite a hard disk's sectors. Un Format cannot recover a hard disk formatted with either of these versions of MS-DOS. There also are many other specialized formatting programs that overwrite a hard disk's sectors. These programs modify the structure of a hard disk in efforts to change or improve its performance. Un Format can't recover a hard disk after being formatted by one of these programs. Luckily, the programs that Un Format cannot protect against usually don't automatically format a hard disk. It is unlikely that you could accidentally format your disk with one of these programs. The Professional Master Key Utilities, version 3.2 Page 36 Un Format So, why can't a floppy disk be Un Formatted? Un Format can be used to save and restore a floppy disk's boot sector, FAT, and root directory. However, it cannot recover the rest of the floppy disk which has been physically eliminated. Although Un Format cannot recover a floppy disk after it is formatted, it has another equally important purpose. Un Format can be used to save a floppy disk's boot sector, FAT, and root directory prior to changing something in one of these areas with PMK. Then, if a mistake is made, that area of the floppy disk can be restored to try again. Using Un Format Prior to using Un Format, copy the file, "UF.EXE," to a blank formatted disk and label that disk as your Un Format disk. Because Un Format is a preventative program, it has to be used regularly to be effective. I recommend two methods for using Un Format on a regular basis. Either of these two methods should protect from an accidental format of your hard disk. Using both methods together provides additional protection. The first method is to run Un Format from your AUTOEXEC.BAT file. By doing this, your hard disk will be saved every time your computer is rebooted. To run Un Format in the AUTOEXEC.BAT file, make sure that your Un Format disk is available in drive B: when your computer starts up. Insert the following line in your AUTOEXEC.BAT file: UF /SAVE c: The next method is to create a .BAT file that will run Un Format before formatting your hard disk. This lets you restore the hard disk even when you did intend to format it. Rename FORMAT.COM to NFORMAT.COM and create the file FORMAT.BAT as shown below. echo off if "%1" == "" goto UnFormat if "%1" == "C:" goto UnFormat if "%1" == "c:" goto UnFormat goto formatt :UnFormat echo Insert the Un Format diskette in drive B: Pause UF /SAVE c: :formatt nformat %1 %2 %3 %4 The Professional Master Key Utilities, version 3.2 Page 37 Un Format Recovering from an accidental format If an accidental format does happen, put your Un Format disk in drive B: and restore the hard disk by typing: B:UF c: Prior to restoring a hard disk, Un Format checks to make sure this is really what you want to do. It shows the following and asks if it is ok to continue. Restoring drive C:'s boot sector, FAT, and root directory from the saved file. This could ruin drive C:'s contents if files are present. Is this ok? (Y/N) Un Format should be used to recover only the same disk that was previously saved. Restoring a different disk would render all of the data on that disk unusable. Any files that existed on the different disk will not be accessible. Un Format won't let you accidentally restore a disk whose format differs from the saved disk. It will, however, restore a different, although identically formatted hard disk if you tell it to. Make sure the disk being restored is the same as the disk saved. When Un Format completes, your hard disk should be restored to look like it when Un Format "saved" the disk. All files, except those moved or changed since the disk was saved, should contain their original data. If Un Format didn't save the disk immediately prior to its being formatted, there may be some errors in the File Allocation Table due to new or old files being moved and changed. These errors should be expected and are no reason for concern. To check and correct for these errors, type: CHKDSK /f c: The Professional Master Key Utilities, version 3.2 Page 38 Zero Disk Zero Disk Zero Disk permanently removes all traces of all data from a disk. It eliminates all existing files along with everything else. It can remove all traces of any confidential data anywhere on a disk. When a disk is zeroed, all of its sectors are overwritten with the hex character 00. Once Zero Disk has finished zeroing a disk, there is no way to recover any data that was on it. The complete command to run Zero Disk is: ZERODISK [/Mono ON | OFF | AUTO] [/Bios ON | OFF] d: Examples: ZERODISK nothing happens; a drive specification must be provided. ZERODISK A: zero drive A: after confirmation ZERODISK C: zero drive C: If Zero Disk thinks you want to zero a hard disk, it asks you to confirm that twice /Mono (Toggle monochrome). Whenever you want all screens displayed in monochrome set the /Mono option ON. With the /Mono option ON, two colors are shown regardless of whether your display can show colors. When the /Mono option is OFF, displays are always in vibrant living color. When the /Mono option is AUTO, displays will be in color when a color display is detected or monochrome when a color display isn't found. The default for the /Mono option in the distribution files is AUTO. /Bios (Toggle direct screen writing). Whenever you want all screen writing done using BIOS function calls, set the /Bios option ON. With the /Bios option ON, all screen writing is done using BIOS function calls. This method of display is slower, but will let computers that aren't 100% IBM compatible run the utilities. The /Bios option also may need to be ON to run the programs from within a windowing operating environment. When the /Bios option is OFF, all screen writing is done directly to the screen. The default /Bios option in the distribution files is OFF; to write directly to the screen. The Professional Master Key Utilities, version 3.2 Page 39 Zero Disk d: (drive to zero). This is the drive you want to zero. It must be specified on the command line. The drive letter must be a valid drive on your system. How Zero Disk works Zero Disk works by systematically filling every sector on a disk with the hex character 00. This fully removes data anywhere on a disk without reformatting it. Unlike formatting programs, Zero Disk starts zeroing sectors at the last sector on the disk and works to the front. It does this as a safety feature to minimize the damage if the wrong disk was selected. So, if you stop Zero Disk after running a short time, some data could be intact on the disk. If there weren't many files on the disk, it may mean that all data is still good. To keep the disk usable by MS-DOS, Zero Disk does not wholly zero several sectors. The first sector (the boot sector) is not touched at all, and the first few bytes in the FAT sectors (used to identify a disk) are also left alone. All other sectors aren't preserved in any way. Running Zero Disk Once running, Zero Disk opens a window and displays the following messages (assume drive C: was entered on the command line): All data on drive C: will be completely destroyed Drive C: will be zeroed. Is this ok? (Y/N) And, if Zero Disk thinks there is a chance that the disk you want to zero is a hard disk, it displays another message: Drive C: may be a hard disk. Is this still ok? (Y/N) Press "Y" and Zero Disk will zero the disk. Press "N" and you are returned to MS-DOS. | Once started, you may stop Zero Disk by pressing Esc. The Professional Master Key Utilities, version 3.2 Page 40 Zero File Zero File Zero File permanently removes all traces of a file's data from your disk. It can eliminate all traces of a confidential file's current data from a disk. Unlike deleting a file using the MS-DOS erase command, a file's data, once zeroed by Zero File, cannot be later recovered from the disk. There is no way to restore a file's data once it has been zeroed by Zero File. The complete command to run Zero File is: ZEROFILE [/Mono ON | OFF | AUTO] [/Bios ON | OFF] [/Keep] [/Yes] <filespec> Examples: ZEROFILE nothing happens; a file specification must be provided. ZEROFILE *.BAK zero files in the current directory after approval ZEROFILE \word\letters\XMAS.86 \tmp\*.$$$ zero files in multiple directories ZEROFILE *.LTR /Keep zero files in the current directory after getting approval; don't delete the files after they are zeroed ZEROFILE A:\work*.* /Yes /Bios ON zero files on another drive; no confirmation question will be asked; display using BIOS screen writing functions /Mono (Toggle monochrome). Whenever you want all screens displayed in monochrome set the /Mono option ON. With the /Mono option ON, two colors are shown regardless of whether your display can show colors. When the /Mono option is OFF, displays are always in vibrant living color. When the /Mono option is AUTO, displays will be in color when a color display is detected or monochrome when a color display isn't found. The default for the /Mono option in the distribution files is AUTO. /Bios (Toggle direct screen writing). Whenever you want all screen writing done using BIOS function calls, set the /Bios option ON. The Professional Master Key Utilities, version 3.2 Page 41 Zero File With the /Bios option ON, all screen writing is done using BIOS function calls. This method of display is slower, but will let computers that aren't 100% IBM compatible run the utilities. The /Bios option also may need to be ON to run the programs from within a windowing operating environment. When the /Bios option is OFF, all screen writing is done directly to the screen. The default /Bios option in the distribution files is OFF; to write directly to the screen. /Keep (keep zeroed files). Normally after a file is zeroed by Zero File, its filename is erased. If you would like to keep the name visible on the disk, use the /Keep option. Using this option still removes all traces of the file data, but the file names are left intact in the directory. /Yes (answer yes). Before Zero File actually zeroes a file, it asks you if you really want to zero the file and waits for a "Y" or "N" response before doing anything. The /Yes option is equivalent to replying Yes to this question. Use /Yes with a lot of caution, especially when specifying ambiguous file names like *.COM or *.* since you could accidentally, permanently wipe out entire directories. <filespec> This is the name of the file(s) you want to zero. Zero File requires that some file specification be provided when it is invoked. The file specification can be unambiguous like LETTER.TXT or ambiguous like LETTER.0?? or LETTER.*. The filename can include an entire or partial directory as well as the drive letter where the file(s) are located. Any file zeroed by Zero File will lose all of its data. The file's data cannot be restored later from the disk. The file can be undeleted with Professional Master Key, but the undeleted file will be completely filled with the hex character 00. Be careful before zeroing any file and make sure it is the file you want to zero. The Professional Master Key Utilities, version 3.2 Page 42 Tiny Edit Tiny Edit is a small text editor that can be used to prepare data files and Batch files and to customize AUTOEXEC.BAT and CONFIG.SYS files. The advantage that Tiny Edit has over EDLIN is enormous; EDLIN is a line editor that makes you sweat blood to get a file changed whereas Tiny Edit is a full screen editor that lets you move around the screen at will, changing text as you go in a natural manner. The advantage that Tiny Edit has over other text editors and word processors is the small size. To this end, Tiny Edit has been created specifically to take as little space on a disk as possible. TinyEdit has a maximum file capacity of 79 characters wide and 792 lines long. Most features of the more popular shareware QEdit or retail Brief or Kedit products have been left out in order to keep it small. We do not want to compete with these other text editors and can heartily recommend them to you if you need more power. The complete invocation for Tiny Edit is: TINYEDIT <filename> [/View] Examples: TINYEDIT C:\AUTOEXEC.BAT Edit the file AUTOEXEC.BAT in the root directory of your C: drive. TINYEDIT PMK-READ /V View (only) the file PMK-READ.1ST. Note that the Monochrome and Bios toggles included in all of the other PMK Utilities have been left out here in order to save space. Using Tiny Edit in Edit Mode As you bring up a text file, you will see the first 21 lines of the file on the screen. You can move your cursor with the arrow keys to anyplace in the text and modify characters at will. To add text to the end of lines, press <End> and type the characters needed to lengthen the line. When you start, you will be in Edit Mode with Insert ON. As you type data into the file, everything to the right of the cursor will be moved over to fit in the new data. To turn Insert OFF, press <INS>. This will put you in an overtype mode. <PgUp> and <PgDn> will show and allow editing the previous and next 21 lines. <F7> and <F8> add and delete lines. | The <Esc> key is an "Undo" that restores the current line to the way it was before any changes were made. Once the cursor is moved off the line, this "Undo" is no longer effective. The Professional Master Key Utilities, version 3.2 Page 43 Tiny Edit | When you quit, the <Esc> key will bring up a question Save Changes ? _ At this time, a "Y" will save the altered file, and an "N" will quit without changing. For a complete list of Edit keys, press <F1>. <F2> will switch to a View mode where you cannot alter the contents of the data, just page up and down to view it. Using Tiny Edit in View Mode In View Mode, Tiny Edit allows only scrolling up and down through files and printing screens and files with the <F3> and <Shift F3> keys. <F2> will take you to Edit Mode if necessary. The /V switch, will enter Tiny Edit in View Mode. The Professional Master Key Utilities, version 3.2 Page 44 Appendix A: Error Messages Appendix A: Error Messages This appendix contains a list of the error messages you may encounter while running one of the programs in The Professional Master Key Utilities. Errors common to all of the programs are listed and explained in this section. Other errors, specific to each program, are described in separate sections. If you find an error that isn't covered in any of these sections or find a program operating differently from the way you think it should, please write what happened or what your problem is and tell us about it. In your problem report, please provide at least the following information. -- name and version number of the program having a problem. -- type of computer you are using. -- version of MS-DOS or PC-DOS you are using (use the MS-DOS VER command to find out). -- free memory your computer has (use the MS-DOS CHKDSK command to find out). -- the names of any memory resident programs running. -- type of disk(s) the problem happened with. Please provide a copy of the Information screen (using PMK) for each disk, if possible. -- what you were doing when you first noticed the problem. Please be as specific as possible. Does the problem happen consistently? Can you duplicate the problem on different disks? Common Errors The only error common to all of the programs deals with running out of memory. When one of the programs needs more memory than is available, it clears the screen and shows a message similar to: Professional Master Key has run out of available memory. See your manual for help and suggestions. Running out of available normally is not a problem. Having 128k of free memory is usually sufficient to run all of the programs without errors. PMK is the most memory hungry program and should show signs of trouble only if run on a hard disk with an enormous number of files and sub-directories and very little available memory. (My hard disk contains 144 sub-directories and 2342 files and doesn't cause any trouble.) In normal use, you shouldn't need more than 128k of free memory. The Professional Master Key Utilities, version 3.2 Page 45 Appendix A: Error Messages There are several solutions available if you do run out of available memory. If you don't have a full 640k of standard memory installed in your computer, the easiest remedy is to purchase and install more memory. If you already have 640k of standard memory installed, try to remove a few memory resident programs from memory. If necessary, reboot your computer and run the problematic program again. Removing memory resident programs leaves more free memory to run The Professional Master Key Utilities. Finally, when running the programs within a multi-tasking environment, change the .PIF or similar program description file for the program. Allocating more minimum memory for the program should help it run better. The Professional Master Key Utilities, version 3.2 Page 46 Appendix A: Error Messages Professional Master Key Professional Master Key > Disk Error < MS-DOS Reported Disk Errors The messages describing disk errors MS-DOS finds are: The disk is write protected. Invalid drive number. Disk drive not ready (door open, no disk, etc). CRC error -- bad parity check. Error during a disk seek. Unable to determine the disk format. Bad sector -- not found on the disk. Error during a disk write operation. Error during a disk read operation. A general disk error happened. The working drive doesn't exist. Since these messages are fairly self-explanatory, I'll avoid a lengthy discussion about the different types of disk errors MS-DOS identifies. Instead, I'll briefly explain the more common errors you may find find with your disks. Many common errors are found on hard disks and many "copy protected" floppy disks since it is normal for them to have a few bad or unusable sectors. These sectors may be located anywhere on the disk, but shouldn't be found within an existing file. While using the Disk Edit function on a hard disk, if one of the above error messages displays, expect it and don't worry. However, if you find a bad sector on a floppy disk or while using the File Edit function, you should be alarmed. There should never be any bad sectors on a typical floppy disk or within a file. A common user error occurs by trying to use PMK on non MS-DOS disks. Professional Master Key is intended only for use with MS-DOS disks and may report a variety of errors when used on non MS-DOS disks. PMK should not be used to edit disks from other operating systems or disks that don't conform to the exact MS-DOS format. PMK Reported Disk Errors The disk errors Professional Master Key reports are due to a disk appearing differently from what was expected or due to a disk being larger than it can handle. These error messages do not necessarily indicate anything wrong with your disks, but should be considered mainly informational. The Professional Master Key Utilities, version 3.2 Page 47 Appendix A: Error Messages Professional Master Key The disk ID byte isn't valid for a DOS disk. PMK checks every disk it uses to make sure it is a MS-DOS disk. One of the things it checks is the FAT's identification byte. If this byte doesn't appear to be valid, the above message is shown. Normally, this error only appears when accessing non MS-DOS disks or MS-DOS disks that have been damaged. The selected directory wasn't found on the disk. Before reading file names from a directory, PMK checks to see if the directory still exists on the disk. If it can't find the directory, you will see the above message. This usually means that you switched disks without Changing the current disk. The selected file wasn't found on the disk. This error message is similar to the previous message. It normally indicates a disk was changed without telling PMK. > File Error < The selected file cannot be renamed to a file name that already exists. A file's name cannot be changed to a name that is already present in the current directory. Enter another name for the file. You cannot erase a sub-directory from within Professional Master Key. Professional Master key won't let you erase a sub-directory name or a remove an empty sub-directory. You need to use the RMDIR command from the MS-DOS prompt to remove a directory. The selected file can't be Undeleted. It's first cluster is being used by another file. The Professional Master Key Utilities, version 3.2 Page 48 Appendix A: Error Messages Professional Master Key The first part of the file selected to be Undeleted has been overwritten by another file. In this case, it is almost impossible to easily recover all of the file's remaining data, so it isn't attempted. The selected file can't be Undeleted. It's allocation chain can't be restored. There wasn't enough free space on the disk to completely Undelete the selected file. This usually means that although the first part of the file may still be intact, it is likely that the file has been overwritten. None of the restored clusters are saved. The selected file can't be edited. It contains no data. The file has a file size of 0 (zero) bytes and has no data, so it isn't meaningful to edit it. Errors While Searching For Text in a Disk or File > Disk Error at sector xxxxx < The error messages shown during a text search of a disk or file are identical to the MS-DOS reported disk errors. For most disk errors, the text search continues, showing the appropriate error message and the additional message: Continuing... However, for the following two errors, the search is ended: Invalid drive number. Disk drive not ready (door open, no disk, etc). The Professional Master Key Utilities, version 3.2 Page 49 Appendix A: Error Messages Full Screen File Sort Full Screen File Sort > Disk Error < The MS-DOS error messages File Sort shows when it reads a hard disk are the same as the MS-DOS reported disk errors described in the PMK error section entitled, "MS-DOS Reported Disk Errors." Since File Sort only reads the FAT, root, and sub-directory areas of a disk, any MS-DOS error message shown probably means that the disk is badly damaged and may be unusable to MS-DOS. MS-DOS normally does not allow bad sectors in the FAT, or any directory areas. The working drive doesn't exist When supplying the complete path of the directory to sort, be sure you use a drive letter that exists on your system. Thus, if you had only four drives available, a drive E: probably wouldn't exist. The selected directory wasn't found on the disk The directory you supplied was invalid or merely misspelled. Check the spelling of the directory and try to run File Sort again. The Professional Master Key Utilities, version 3.2 Page 50 Appendix A: Error Messages Fill Disk Fill Disk > Disk Error < The MS-DOS error messages Fill Disk shows when it reads a hard disk are the same as the MS-DOS reported disk errors described in the PMK error section entitled, "MS-DOS Reported Disk Errors." > File Error < FILLDISK.$$$ wasn't found on the disk. Somehow, the disk being filled has changed or was switched before Fill Disk could delete its temporary file. FILLDISK.$$$ is read only. The file, FILLDISK.$$$ already exists in the current directory and has a read only attribute. Toggle its read only attribute off with PMK and run Fill Disk again. There are too many open files. Fill Disk cannot open its temporary file. All available file handles are being used by another program. Run Fill Disk by itself or increase the FILES=xx statement in your CONFIG.SYS file.

The program being installed couldn't be found in the current directory. All programs being installed must be located in the current, default directory. The filename is read only. The program being installed has a read only attribute and cannot be modified. Toggle its read only attribute off with PMK and try to install it again. There are too many open files. Install cannot open the program file to install. All available file handles are being used by another program. Run Install by itself or increase the FILES=xx statement in your CONFIG.SYS file. > Installation Error < The color configuration area wasn't found. The options configuration area wasn't found. For either of these two errors, the respective configuration areas couldn't be found in the program file being installed. These messages imply that the program being installed might have had an unauthorized modification and may no longer work correctly. Do not use any of The Professional Master Key Utilities programs if you suspect that they have been modified. The Professional Master Key Utilities, version 3.2 Page 52 Appendix A: Error Messages Un Format Un Format > Disk Error < The MS-DOS error messages Un Format shows when it reads a hard disk are the same as the MS-DOS reported disk errors described in the PMK error section entitled, "MS-DOS Reported Disk Errors." Since Un Format only reads the boot sector, FAT, and root directory areas of a hard disk, any MS-DOS error message shown probably means that the hard disk is badly damaged and may be unusable to MS-DOS. MS-DOS does not permit bad sectors in the boot sector, FAT, or root directory areas. The disk ID byte isn't valid for a DOS disk. Un Format checks the hard disk to save/restore prior to saving/restoring it to make sure it is a valid MS-DOS disk. One of the things it checks is the FAT's identification byte. If this byte doesn't appear to be valid, the above message is shown. > File Error < The save file wasn't found on the disk. The file, "B:\UNFORMAT.PMK," couldn't be found. Make sure the disk with that file is in drive B: and run Un Format again. The save file is read only. The file, "B:\UNFORMAT.PMK," has a read only attribute and cannot be modified. Toggle its read only attribute off with PMK and run Un Format again. There are too many open files. Un Format cannot open the file, "B:\UNFORMAT.PMK." All available file handles are in use by another program. Run Un Format by itself or increase the FILES=xx statement in your CONFIG.SYS file. There is no space on the save disk. Drive B: doesn't have enough free space on it to write all of the file, "B:\UNFORMAT.PMK." Delete a few files from that disk or use a newly formatted disk in its place. The Professional Master Key Utilities, version 3.2 Page 53 Appendix A: Error Messages Zero Disk Zero Disk > Disk Error < > Disk Error at cluster xxxxx < The MS-DOS error messages Zero Disk shows when it zeros a disk are the same as the MS-DOS reported disk errors described in the PMK error section entitled, "MS-DOS Reported Disk Errors." Some errors should be expected when zeroing a hard disk. It is normal for a hard disk to have a few areas containing bad sectors. No errors should exist on a floppy disk however. If a disk error happens on a floppy disk, that disk should not be used and should be discarded. Zero Disk continues zeroing a disk after all errors with the exception of the following two errors: Invalid drive number. Disk drive not ready (door open, no disk, etc). The disk ID byte isn't valid for a DOS disk. Zero Disk checks the disk to zero prior to zeroing it to make sure it is a valid MS-DOS disk. One of the things it checks is the FAT's identification byte. If this byte doesn't appear to be valid, the above message is shown. Normally, this error appears only when accessing non MS-DOS disks or MS-DOS disks that have been damaged. The Professional Master Key Utilities, version 3.2 Page 54 Appendix A: Error Messages Zero File Zero File > File Error < The file wasn't found on the disk. File: \PATH\FILENAME.EXT wasn't found. Both of these messages indicate that the file you wanted to zero wasn't found on the disk. Recheck the correct name for the file and run Zero File again. There are too many open files. Zero File cannot open the file to zero. All available file handles are being used by another program. Run Zero File by itself or increase the FILES=xx statement in your CONFIG.SYS file.
