- PURPOSE
-
- DiskInfo is a tool which can be used to display information about any Amiga
- storage media, including disks, hard disks and memory. It is capable of
- creating global environmental variables which can be used by any AmigaDOS
- or ARexx script. It can be executed as an AmigaDOS command from either the
- Workbench or the Shell.
-
- The goal of this program is to evolve into worthy replacement for the
- Workbench "c:Info" command.
-
-
-
-
-
- FEATURES
-
- The following are the main features of this program:
-
- - Displays device capacity, usage, and available space in bytes and
- blocks (also shows bytes per block)
-
- - Creates global environmental variables usable by ARexx and AmigaDOS
-
- - Recognizes and displays the following Amiga file systems:
- DOS0: Standard ("Old") File System (OFS)
- DOS1: Fast File System (FFS)
- DOS2: Standard File System, International mode (OFS)
- DOS3: Fast File System, International mode (FFS)
- DOS4: Directory Caching Standard File System, International
- mode (DC-OFS)
- DOS5: Directory Caching Fast File System, International
- mode (DC-FFS)
-
- - Shows current device status (validated, validating, read only)
-
- - Workbench 2.04, 2.1, and 3.0 compatible
-
- - Standard command line parsing conforming to "Amiga User Interface
- Style Guide"
-
- - Enforcer "Hit Free"
-
-
-
-
-
- REQUIREMENTS
-
- For this program to operate properly, you must have the following:
-
- - An Amiga (any model)
-
- - Workbench 2.04, Workbench 2.1, or Workbench 3.0
-
- - A working knowledge of the Workbench or Shell environments
-
- - The DiskInfo program
-
-
-
-
-
- USAGE
-
- This program may be executed from the Workbench using the "Workbench/
- Execute Command..." option, or from the Shell. Usage is the same from
- either environment:
-
- DiskInfo <device> [SETENV [BytesPerBlock][DiskName][DiskStatus]
- [DiskType][Errors][FreeBlocks][FreeBytes][InUnit][InUse]
- [PercentFull][SizeBlocks][SizeBytes][UsedBlocks]
- [UsedBytes][All]] [QUIET]
-
-
- The "<device>", of course, is the name of any storage device or volume. The
- other arguments shown below are explained later in this manual. If no
- device is specified or if any argument is improperly used, the following
- will be displayed:
-
- DiskInfo (Version 1.20) by Gregg Giles
- Purpose: Gives a complete status report on any mounted AmigaDOS device.
- Usage : DiskInfo <device> [SETENV [BytesPerBlock][DiskName][DiskStatus]
- [DiskType][Errors][FreeBlocks][FreeBytes][InUnit][InUse]
- [PercentFull][SizeBlocks][SizeBytes][UsedBlocks][UsedBytes][All]]
- [QUIET]
-
-
-
-
-
- USAGE EXAMPLES
-
- These examples assume that you have booted from your Workbench 2.04
- distribution disk, and your Extras disk is in DF1:. Issue this command:
-
- 1> DiskInfo DF0:
-
- Most information of interest to the average user will be displayed, and
- will appear like this (or similar to it):
-
- Name : Workbench2.0: Errors : 0 Bytes Blocks
- Status: Write Protected Full : 94.20 % Size: 857904 1758
- Type : Amiga OFS (DOS0) In Unit: 0 Used: 808128 1656
- Block : 488 bytes In Use : Yes Free: 49776 102
-
- Issuing the following command will show what resides on the Extras disk:
-
- 1> DiskInfo DF1:
-
- Something similar to the following will appear:
-
- Name : Extras2.0: Errors : 0 Bytes Blocks
- Status: Write Protected Full : 84.64 % Size: 857904 1758
- Type : Amiga OFS (DOS0) In Unit: 0 Used: 726144 1488
- Block : 488 bytes In Use : Yes Free: 131760 270
-
- This, of course, is assuming that no errors occur. Further explanation of
- each field can be found in the section "Explanation Of Fields".
-
- Logical devices created using the "Assign" command may be used in place of
- a physical storage device (ie: "c:", "libs:", "devs:", etc.) However, in
- such cases, information about the physical media on which that logical
- device resides will be displayed.
-
- For example, assuming you booted from your Workbench 2.04 distribution
- disk, use this command and view the ensuing results (notice that the "name"
- field gives the complete path to the logical device specified):
-
- 1> DiskInfo C:
-
- Name : Workbench2.0:C Errors : 0 Bytes Blocks
- Status: Write Protected Full : 94.20 % Size: 857904 1758
- Type : Amiga OFS (DOS0) In Unit: 0 Used: 808128 1656
- Block : 488 bytes In Use : Yes Free: 49776 102
-
- In order to quiet all output to the console, use the QUIET flag. Only error
- messages and usages templates are not suppressed by this flag. The
- following example has the result of accomplishing nothing (even redirection
- of output would be pointless here):
-
- 1> DiskInfo WORK: QUIET
-
- To create environmental variables, the argument SETENV must always be
- supplied. The following example will create variables for the disk's name,
- the disk's type, the number of blocks used, the number of bytes free, and
- the number of errors on the disk:
-
- 1> DiskInfo WORK: SETENV DiskName DiskType UsedBlocks FreeBytes Errors
-
- Global environmental variables of the same names will then be created
- automatically in the "ENV:DiskInfo" directory. If there are any errors,
- then you will be notified.
-
- In order to create all possible environmental variables, use the following
- command. This time, we wish to make sure there is no output to the console
- (ie: the screen), so we'll use the QUIET flag:
-
- 1> DiskInfo SYSTEM: SETENV ALL QUIET
-
- Other examples of using DiskInfo include:
-
- Command Shows information about...
-
- DiskInfo DF0: Disk in unit 0 (DF0:)
- DiskInfo DF1: Disk in unit 1 (DF1:)
- DiskInfo DF2: Disk in unit 2 (DF2:)
- DiskInfo DH0: Hard disk partition DH0:
- DiskInfo DH1: Hard disk partition DH1:
- DiskInfo RAM: The RAM: disk
- DiskInfo RAD: The RAD: disk
- DiskInfo Extras2.0: A volume named "Extras2.0"
- DiskInfo Pictures1: A volume name "Pictures1"
-
-
-
-
-
- EXPLANATION OF FIELDS AND GLOBAL ENVIRONMENTAL VARIABLES
-
- The program displays rougly a dozen fields when executed (assuming there
- are no errors). "Field" refers to the name of the field shown when the
- program is executed normally. "Variable" shows the complete path of the
- global environmental variable created when "Argument" is supplied by the
- user as part of the command line. (For more information on how to create
- and make use of global environmental variables, see the sections "Usage
- Examples", "Using Global Environmental Variables (AmigaDOS and ARexx)",
- "Appendix 1: Using DiskInfo With An ARexx script", and "Appendix 2: Using
- DiskInfo With An AmigaDOS Script" in this manual.)
-
- All possible fields and their corresponding environmental variables are
- described as follows.
-
- Field : NAME
- Argument: DiskName
- Variable: ENV:DiskInfo/DiskName
- Purpose : Name of the disk (or volume) being examined.
- Output : A valid Amiga disk name. If a logical device name is given, a
- full path name will be displayed.
-
-
- Field : STATUS
- Argument: DiskStatus
- Variable: ENV:DiskInfo/DiskStatus
- Purpose : Physical status of the disk.
- Output : Possible results include:
-
- "Write Protected":
- Disk is write protected and can only be read from, not written to.
- This also means that files on the disk can not be edited or deleted.
- "Validating":
- The disk's structure has been corrupted, and AmigaDOS is attempting
- to correct the problem.
- "Validated":
- The disk's structure is stable, and thus can be written to or read
- from. Files can be edited and deleted.
- "Unknown":
- The disk's status cannot be determined.
-
-
- Field : TYPE
- Argument: DiskType
- Variable: ENV:DiskInfo/DiskType
- Purpose : Type of disk.
- Output : Possible results include:
-
- "Amiga OFS (DOS0)":
- The Standard File System format which appeared on the original
- Amiga 1000 and which is still in use. Also known as the "Old File
- System" (OFS). All disks formatted using the "Format" command under
- Workbench 1.0-2.04 were, by default, OFS format disks. OFS uses 488
- bytes per block, and is rather slow.
- "Amiga FFS (DOS1)":
- The Fast File System (FFS) format introduced in Workbench 1.3 (for
- hard disk users only). Workbench 2.04 introduced the capability to
- format disks using FFS. The main goal of FFS was to speed up seek
- times. Workbench 2.04-3.0 are capable of formatting FFS disks. FFS
- uses 512 bytes per block, and is faster than FFS.
- "Amiga OFS (DOS2)":
- The "International" version of the Standard File System (OFS). This
- version of the filesystem resolves bugs present in the original OFS
- (DOS0). Has the same features of OFS (DOS0). Introduced in Workbench
- 2.1, and present in Workbench 3.0.
- "Amiga FFS (DOS3)":
- The "International" version of the Fast File System (FFS). This
- version of the filesystem resolves bugs present in the original FFS
- (DOS1). Has the same features of FFS (DOS1). Introduced in Workbench
- 2.1, and present in Workbench 3.0.
- "Amiga DC-OFS (DOS4)":
- The Disk Caching version of the Standard File System (OFS)
- introduced in Workbench 3.0. The main goal of DC-OFS is to speed up
- 3.5" disk access times. Uses 488 bytes per block.
- "Amiga DC-FFS (DOS5):"
- The Disk Caching version of the Fast File System (FFS) introduced in
- Workbench 3.0. The main goal of DC-FFS is to speed up 3.5" disk
- access times. Uses 512 bytes per block.
- "Unknown (????)":
- The format of the disk cannot be determined. Possibly a disk format
- not known about at the time of the creation of this program.
-
- Note: Subsequent versions of this program may be able to recognize the
- following disk types: BAD (unreadable/corrupted), KICK (Amiga Kickstart
- disk), NDOS (format of the disk is good, but it does not use any known
- AmigaDOS format; possibly a proprietary file format such as those often
- used as copy protection for games).
-
-
-
- Field : BLOCK
- Argument: BytesPerBlock
- Variable: ENV:DiskInfo/BytesPerBlock
- Purpose : The number of bytes that compose one block on the disk.
- Output : A positive numeric value.
-
-
- Field : ERRORS
- Argument: Errors
- Variable: ENV:DiskInfo/Errors
- Purpose : Number of read/write errors on the disk.
- Output : A positive numeric value.
-
-
- Field : FULL
- Argument: PercentFull
- Variable: ENV:DiskInfo/PercentFull
- Purpose : Percentage of the disk which is full.
- Output : A positive numeric percentage (accurate to the hundredth of a
- percent).
-
-
- Field : IN UNIT
- Argument: InUnit
- Variable: ENV:DiskInfo/InUnit
- Purpose : AmigaDOS unit number in which the disk resides.
- Output : Possible results include:
-
- -1: The RAM: device
- 0 : Floppy disk DF0:
- 1 : Floppy disk DF1:
- 2 : Floppy disk DF2:
- x : Any unknown unit number, where (x) is the number of that unit.
- (Note: Some hard disk partitions may appear as unit 0.)
-
-
- Field : IN USE
- Argument: InUse
- Variable: ENV:DiskInfo/InUse
- Purpose : Message telling if the disk is currently in use.
- Output : Possible results include:
-
- "Yes": The disk is in use.
- "No" : The disk is not in use.
-
-
- Field : SIZE (BYTES)
- Argument: SizeBytes
- Variable: ENV:DiskInfo/SizeBytes
- Purpose : Total byte storage capacity of the disk.
- Output : A positive numeric value. Note that this is the total actual
- storage possible. The Amiga file system will reduce the total
- available free storage space.
-
-
- Field : SIZE (BLOCKS)
- Argument: SizeBlocks
- Variable: ENV:DiskInfo/SizeBlocks
- Purpose : Total block storage capacity of the disk.
- Output : A positive numeric value.
-
-
- Field : USED (BYTES)
- Argument: UsedBytes
- Variable: ENV:DiskInfo/UsedBytes

- USING GLOBAL ENVIRONMENTAL VARIABLES (AMIGADOS AND AREXX)
-
- Global environmental variables were introduced to the Amiga operating
- system under Workbench 1.3, and are becoming commonly used by more and more
- applications. These variables are created by various applications so that
- other applications and scripts can make use of their contents. For example,
- the Workbench creates two environmental variables: "Workbench" and
- "Kickstart". The environmental variable "Workbench" contains the version
- number of the Workbench software, and the "Kickstart" version contains the
- version number of the Kickstart ROM chip. (These two variables are useful
- for applications that want to quickly know what version of the operating
- system is being run.) If you would like to view the contents of these
- variables, give the following command in a Shell:
-
- 1> echo Workbench version: $Workbench. Kickstart version: $Kickstart.
-
- All environmental variables are stored in the "ENV:" directory. Some
- applications will create their own directories in ENV: which will store
- variables specific only to that application; DiskInfo does just this. The
- format used to view these variables is as follows (where "Directory_Name"
- is the name of the directory containing the variable, and "Variable_Name"
- is the actual name of the variable):
-
- echo ${ENV:[Directory_Name]/[Variable_Name]}
-
- DiskInfo stores all of its variables in the "ENV:DiskInfo" directory. If
- this directory doesn't exist when the user wants DiskInfo to create
- variables, then it will be automatically created (note: this directory and
- all variables within it are lost when the machine is reset or
- powered-down.) The following Shell commands will create some variables and
- then display them:
-
- 1> DiskInfo RAM: SETENV DISKNAME DISKTYPE USEDBYTES QUIET
- 1> echo ${env:diskinfo/DiskName}
- 1> echo ${env:diskinfo/DiskType}
- 1> echo ${env:diskinfo/UsedBytes}
-
- The first command will tell DiskInfo to create three environmental
- variables called DiskName, DiskType, and UsedBytes (DiskInfo argument names
- will always correspond to the name of the variable created; ie: Supplying
- the argument "DISKNAME" creates a variable called "DiskName", which
- contains the name of the disk in question.) The QUIET flag prevents output
- to the Shell. (This is not necessary in order to create or read variables -
- it is only done here to stop output to the console; that is, to reduce
- clutter on the screen.)
-
- The second through fourth commands will display (one by one) each of the
- three variables just created. This is the exact method that should be used
- in AmigaDOS scripts to create and show DiskInfo variables.
-
- The variables which this program creates are global in scope, which means
- that they can be accessed by any application or any Shell running on the
- system. ("Local" environmental variables have a scope which is limited to
- the Shell from which they were created.) This means that any application or
- script (be it AmigaDOS or ARexx) can quickly make use of the information
- stored in these variables with great ease.
-
- The "Using The System Software" manual provided with your Amiga is the
- definitive resource on environmental variables and how they can be used.
- For that reason, this manual will only detail how to use the variables
- created by this program.
-
- One practical application for the variables created by DiskInfo is in
- script-based disk-catalog programs. If, for example, you created a script
- which was to catalog the names and storage capacity of all of your disks,
- you could have DiskInfo create two variables: one containing the disk name,
- and the other containing the disk capacity. You could then have your script
- read these variables and use them as you desire. (An example of how to
- create and display these variables from an AmigaDOS script is provided in
- Appendix 2.)
-
- ARexx is in itself a powerful and easy-to-use interpreted scripting
- language that is provided with the Amiga operating system (Workbench 2.04
- and later). Using ARexx, users can quite literally design a powerful
- disk-catalog program using the functions made available to them with
- DiskInfo. All the user must do is create the interface using ARexx, and use
- the environmental variables created by DiskInfo to fill in the information.
- For a complete list of disk contents, this user can simply have ARexx call
- the "c:Dir" command - no special programming talent is required! An example
- of how to create and display these variables from an ARexx script is
- provided in Appendix 1.) For additional information on ARexx and how it
- works, refer to the "Using The System Software" manual provided with your
- Amiga system.
-
- Appendix 1 provides a complete example of using DiskInfo's environmental
- variables from an ARexx script. Appendix 2 gives an example of using those
- same variables from an AmigaDOS script. More examples of creating
- environmental variables can be found in the "Usage Examples" section.
-

-
- PROGRAM INTEGRITY AND BUGS
-
- It is the author's goal to keep this program as stable, correct, and as
- bug-free as possible. For this reason it employs careful error checking
- techniques, particularly when dealing with locks and memory. Everything
- which is opened is closed, even when errors occur. As an Amiga user
- himself, the author loves cleanly written programs, particularly those that
- don't suck up system resources when they screw up.
-
- This program has its own built-in error messages, and all are largely
- self-explanitory. These error messages generally only appear when the user
- has done something incorrectly (ie: trying to examine a disk in a drive
- when no disk is present).
-
- However, should you discover any bugs in this program, please record them
- and contact me immediately so that they may be corrected and the fixed
- version of the program released.
-

-
-
- REVISIONS AND PLANNED ENHANCEMENTS
-
- Planned Enhancements:
-
- Enable recognition of disk formats other than AmigaDOS, including MS-DOS
- disks (720k and 1.44MB).
-
- Enable display of all mounted devices simultaneously, much like the
- AmigaDOS Info command when used with no flags.
-
- A Workbench window interface. Due to the increasing number of features that
- will eventually make its way into this code, it might be necessary.
-
- CD-ROM (ISO-9660) support.
-
-
-
- Changes since the previous version:
-
- Recognition of new Amiga-specific file systems added: DOS2, DOS3, DOS4, and
- DOS5.
-
- Added Workbench 2.04 standard command line parsing which conforms to the
- "Amiga User Interface Style Guide". This had the effect of reducing code
- size, system overhead requirements, and permitting the display of a
- standardized template when issuing "DiskInfo ?" at the command line.
-
- Ability to create global environmental variables added. A user may now
- specify any of the following command line parameters (when using the SETENV
- parameter), and a corresponding variable will be created in the
- "ENV:DiskInfo" directory: BYTESPERBLOCK, DISKNAME, DISKSTATUS, DISKTYPE,
- ERRORS, FREEBLOCKS, FREEBYTES, INUNIT, INUSE, PERCENTFULL, SIZEBLOCKS,
- SIZEBYTES, USEDBLOCKS, and USEDBYTES. The argument ALL will prevent users
- from having to type all of the arguments in order to create all possible
- environmental variables.
-
- New argument: QUIET. This argument stops all output to the console, with
- the exception of error messages, the template, and the usage message.
-
- Compatible with Workbench 2.1 and 3.0.
-
-
-
-
-
- APPENDIX 1: USING DISKINFO WITH AN AREXX SCRIPT
-
- While DiskInfo itself does not have an ARexx port, it can be used by ARexx
- as a normal AmigaDOS command. The global environmental variables which
- DiskInfo creates can also be easily read and manipulated by any ARexx
- script. The following is an example of how an ARexx script can both run
- DiskInfo as well as manipulate the global environmental variables which it
- can create.
-
- This ARexx script will run DiskInfo to find information about a disk in
- DF0:, get the DiskName and FreeBytes variables, and then print their values
- to the Shell. (Requires ARexx and Workbench 2.04 or better.)
-
-
-
- --- cut here (begin) ---
-
- /* ARexx script */
- address command
- echo
- echo "Disk information"
- /* Get the name of the disk */
- result = open('MyFile', 'env:DiskInfo/DiskName', 'R')
- NameOfDisk = readln('MyFile')
- result = close('MyFile')
- /* Get the bytes free information */
- result = open('MyFile', 'env:DiskInfo/FreeBytes', 'R')
- FreeBytesOnDisk = readln('MyFile')
- result = close('MyFile')
- echo "The disk named" NameOfDisk "has" FreeBytesOnDisk "bytes free."
-
- --- cut here (end) ---
-
-
-
-
-
- APPENDIX 2: USING DISKINFO WITH AN AMIGADOS SCRIPT
-
- While AmigaDOS scripts are not quite as powerful as their ARexx
- counterparts, they are still useful in manipulating environmental
- variables. The following script will use DiskInfo to get the name of a disk
- and the number of bytes free on it. This information will then be put into
- two environmental variables, which will then be printed to the Shell.
-
-
-
- --- cut here (begin) ---
-
- DiskInfo >nil: df0: SETENV DISKNAME FREEBYTES
- echo "The disk named ${ENV:DiskInfo/DiskName}"
- echo "has ${ENV:DiskInfo/DiskInfoName} bytes free."
-
- --- cut here (end) ---
-
-
-
- The following example is a bit more involved than the first, but it is
- still based upon the same principles of the first: make DiskInfo create all
- of its global environmental variables, and then display them. This script,
- however, does error checking. It a certain variable doesn't exist, then a
- message saying that the variable doesn't exist will be shown.
-

-
- APPENDIX 3: FINDING DISKINFO'S VERSION
-
- DiskInfo's version number can easily be found by using the AmigaDOS
- "c:Version" command as well as by using a question-mark as the only
- argument in the command line.
-
- Using the AmigaDOS Version command:
-
- 1> VERSION DiskInfo
-
- Using DiskInfo to find its own version:
-
- 1> DiskInfo ?
-
- When the argument template appears, simply press RETURN, and information
- about the program will appear (including the version number).
