sensitive help, available at a touch of the ^BF1^B key.

Whenever you are using a dialog box and you want instructions
on how to proceed, press ^BF1^B. When you've got a menu pulled
down, you can move the highlight to any item and press ^BF1^B for
help on that item.

When you are first getting familiar with a Tool, you will
find it helpful to select the ^b[Index]^b button at the bottom of
any help screen. It displays a list of topics, at least
one of which provides background and introductory material.

ZA dialog box is any screen or panel that accepts some sort of
input. With the mouse, dialog boxes are a breeze to use; just
point to anything and ^bClick^b.

With the keyboard, there are a few things to learn, but the 
two basics rules are:

  * Press ^bTab^b or ^BShift^B+^BTab^B to move between groups.
  * Press and hold ^BAlt^B and then press any highlighted 
    ^BL^Better for an ^BAlt^B+^Bkey^B accelerator sequence.

There are several different types of ^bcontrols^b used in the
dialog boxes. They come in ^bgroups^b. One group is always the
^bfocus^b (the area where the keyboard will have an effect).

Norton engineers have made it easy to use the keyboard to get
to these commands. All menu titles have a unique ^bA^bccelerator
key. Press ^BAlt^B and then the accelerator key to directly
access a menu. Furthermore, each item within a menu has its
own accelerator. Press that key to directly execute the menu
command. Or, use ^C1A and ^C1B to move from menu to menu. Use
 and  to highlight an item within a menu and then press Enter
to select it. Press ^bEsc^b if you change your mind. 

In the example above, you can press ^bAlt^b+^BT^B to access the menu
and then ^BD^B to execute the Drive command. In help, you'll see
this keychord sequence referred to in the form ^bAlt^b+^bT^b,^BD^B. Keep
the ^bAlt^b key pressed while you type the first letter. Hold or
release, as convenient, for the second letter.

In the example above, you could also just press the ^BAlt^B+^BF1^B
shortcut without using the menus at all.

As you walk the menu, for in-depth help on that item, just
press ^bF1^b. Or press ^bF1^b at any time and then press ^BI^B to get
to the Help Index.

^BWith a mouse^B, point to any menu name of the menu bar and ^bclick^b

	Norton Disk Doctor runs numerous tests to determine the health
of your disk and warns you if it finds problems. You are given
the option of correcting them. The tests and corrections are
performed automatically, so you need not have any fear even if
the way a computer works is a complete mystery to you.

For extra safety, you can even undo any changes the Disk Doctor
has performed. Norton Disk Doctor also examines the disk for
physical defects and generates a report about your disk. If
testing was interrupted, you can print the report on what
happened so far.

Use the Disk Doctor to diagnose your disk for a variety of
possible disk problems:

  * If you have trouble accessing a disk
  * If you notice problems when you try to run applications
  * If files or directories seem to be missing but were 
    never deleted
  * If your computer does not start and you suspect problems 
    with the boot disk or partition

The ^hNorton Disk Doctor^h main screen, which appears when you
first start the program, lets you set Disk Doctor to work.

Practice preventive maintenance by running Norton Disk Doctor
daily. Make sure the following line appears in your AUTOEXEC.BAT
file:

  ^BNDD /Q^B

The Disk Doctor will run a quick test of your hard disk every
time you start your computer.
Norton Disk Doctor (NDD) automatically diagnoses and repairs
damaged disks. It runs numerous tests to determine the
integrity of all parts of a disk. When it finds a problem, it
tells you about it and fixes it (at your option). It prints
a detailed report about your disk and all problems found and
all measures taken to correct them.

In this screen, you are given five options. Use ^B^B and ^B^B to
highlight an option and press ^BEnter^B to select it.

^bDiagnose Disk^b: Select this first. You will be prompted to
 select one or more of your drives and then Norton Disk Doctor
 will begin its comprehensive diagnosis. If Norton Disk Doctor
 finds an error, you can choose to fix the problem or leave it
 alone.

^BSurface Test^B: This test verifies the readability of disk 
 sectors and is usually run automatically after Diagnose Disk.
 If you are having trouble with elusive read errors, you can
 jump straight to the surface test.

^bUndo Changes^b: When Norton Disk Doctor fixes a problem, it can
 save the original data of anything it changes (it creates an
 "undo" file, typically on a different disk). You will use this
 only option if you want to change a disk back to its previous
 condition before Norton Disk Doctor changed the disk.

^bOptions^b: This button lets you preselect surface-testing
 options, skip certain tests (some take a long time or may not
 be compatible with your system), and create a custom message
 to be displayed when Norton Disk Doctor finds a problem. 

^bQuit Disk Doctor^b: Select this when you have finished using
 Norton Disk Doctor.
This dialog box lets you pick which drives you want Norton Disk
Doctor to diagnose and repair.

^BTo pick a single drive:^B
  * Use ^B^B and ^B^B to highlight the drive name and then 
    press ^BEnter^B. Testing will begin immediately.

^BTo pick two or more drives:^B
  * Use ^B^B and ^B^B to highlight a drive and press ^BSpacebar^B
    to mark it for diagnosis. A check mark is displayed by each
    drive you have selected. 
  * Press ^BEnter^B to begin diagnosing the first disk that's tagged
    with a checkmark. When Disk Doctor is finished with that
    disk, it begins on the next.

With a mouse, click on any drive you want tested and then select
the [Diagnose] button.
Select this command to exit (or just press Esc).

This screen displays the actions Norton Disk Doctor takes as
it diagnoses your disk. If all goes well, you need do nothing
while this screen is displayed.

If NDD discovers a problem, it describes that problem,
recommends an action, and lets you choose to have the problem
fixed or leave it in place. ^BIt is always best to let the^B
^BDoctor fix your disk.^B All changes can be undone, so even in
the rare case where the Doctor slips a stitch, you can easily
get back to the original state.

^bAnalyzing Boot Record^b tests the readability and contents of
 the very first sector on the diskette (or hard disk ^hpartition^h).
 This sector contains the DOS start-up program and important
 information about the disk.

^bAnalyzing File Allocation Tables^b tests the readability and
 verifies the authenticity of both copies of the ^hFAT^h.

^bAnalyzing Directory Structure^b looks at each directory on the
 disk to make sure it is readable and is, in fact, a
 directory. This also makes sure that the special directory
 entries ^b.^b and ^b..^b really link to self and parent.

^bAnalyzing File Structure^b checks each file entry in each
 directory, looking for oddities and invalid entries.

^bAnalyzing Lost Clusters^b makes sure that each entry in each
 directory correctly links into the FAT, that each FAT chain
 is unbroken, that each chain is owned by a single file, and
 no ^hlost clusters^h exist.
This screen summarizes the test results and problems found for
the selected disk.

Select ^b[Report...]^b (just press Enter) for detailed information
on the disk and problems found. If any problems came up, it
is wise to print a report for future reference.

Select ^b[Done]^b (or just press ^BEsc^B) to skip the report and get
back to the opening screen. If you previously specified to
diagnose more than one disk, the analysis for the next disk
will begin immediately.
The Disk Doctor report is a scrolling list of text describing
the disk and documenting the test results.

Use ^B^B and ^B^B and ^BPgDn^B and ^BPgUp^B to examine the report on screen.
Select ^b[Done]^b or press ^BEsc^B when you are finished reviewing the
report.

Select ^b[Print]^b to send the text directly to your printer.

Select ^b[Save As...]^b if you wish to save the report as a
text file. You are prompted for a filename and the text is
saved so you can review it or print it out later.

  ^bWarning:^b Don't save the report to a damaged disk!
This dialog box lets you reverse any action taken by the Disk
Doctor in its most recent session.

  ^BNote:^B You should use this only option in the ^Brare case^B that
  a correction made by Disk Doctor did not provide satisfactory
  results and you wish to fix the disk manually.

When Norton Disk Doctor is about to fix your disk, it will first
ask if you want to save an "^BUndo File^B." When you do, a file named
^BNDDUNDO.DAT^B is saved in the root directory of a drive you
choose. If you later use Undo Changes, the undo file is located
and its contents are used to restore any disk data changed by
the Doctor (have you ever heard of a reversible tonsillectomy?).

  ^BWarning:^B The Doctor tries to ensure that the undo can be
  applied correctly, but in any case, you should NOT use undo if
  you have performed any file-writing operations on the target
  disk since the time the Undo file was created.
	
Use ^B^B and ^B^B to highlight a button and press ^BEnter^B to bring up
that dialog box. Press ^BEsc^B to return to the NDD Main screen.

^hSurface Test^h lets you set options to shorten or prolong the
 most time-consuming of the tests made by the Doctor. It also
 lets you set up for weekly "deep" testing when you use Norton
 Disk Doctor on a daily basis.

^hCustom Message^h is designed for use by PC coordinators and
 MIS personnel so novice users aren't intimidated by any of the
 technical messages displayed when Norton Disk Doctor discovers
 a problem. When activated, a non-technical operator can't make
 corrections to any disk.

^hTests to Skip^h lets you customize some testing so that you
 can benefit from Norton Disk Doctor even if parts of your
 system are not entirely compatible with existing standards.

^hSave Options^h lets you save the settings of any options you
 have selected. After saving, these settings will be the
 defaults each time you run NDD.
$Use ^B^B and ^B^B to move from option to option or use ^BTab^B to move
from group to group. Press ^BSpacebar^B to select one option in
each group. Press ^BEnter^B to accept the settings or ^BEsc^B to
cancel.

These options pertain to the often time-consuming tests Norton
Disk Doctor makes to verify the readability of disk sectors.

^b─── Test ────────────^b
  * ^BDisk Test^B verifies all parts of the disk. 
  * ^BFile Test^B is faster, but it verifies only those parts of
    the disk which are currently in use by files or directories.

^b─── Test Type ───────^B 
  * ^BDaily^B selects a "quick scan" of the disk that checks
    data on each track, but does not actually verify each and
    every sector. 
  * ^BWeekly^B does perform a comprehensive read of every sector;
    it takes two to three times longer than Daily. 
  * ^BAuto Weekly^B is a great compromise. When Disk Doctor is run
    on any Friday, the full Weekly test type is performed, but
    on other days of the week, the quick-scan Daily test is used.

^b─── Passes ──────────^B
  * ^BRepetitions [...]^B lets you specify how  many times NDD
    should perform the surface test. Move the cursor to the text
    box and type a number from 0 to 999.
  * ^BContinuous^B keeps repeating the test until you stop it by
    pressing ^BEsc^B. You might use these options to flush out an
    intermittent bad sector, which might not show up without
    repeated testing.

^b─── Repair Setting ──^B
  Disk Doctor repairs surface problems by moving whatever part
  of the data is readable to a good part of the disk and marking
  as bad in the ^hFAT^h the area that it came from.
 
  * The normal setting is ^BPrompt before Repairing^B, which lets
    you decide how to proceed with each surface-testing error.
  * If you don't want this action, select ^BDon't Repair^B. 
  * If you intend to let the surface test run unattended
    continuously or with numerous repetitions, you can select
    ^BRepair Automatically^B. This lets Norton Disk Doctor repair
    surface errors as it finds them and resume immediately. The
    Disk Doctor diagnosis report will list all errors.
While the Doctor is performing surface diagnosis, this screen
monitors the progress. Press ^BEsc^B at any time to pause the
test (and, optionally, cancel the rest of the test).

In the disk map, each block, such as ▒, represents a portion
of the disk (a ^bLegend^b on the screen identifies the different
characters). The actual amount of data represented by a block
varies, depending upon the size of the disk. The blocks in a 
Bold color (such as ^b▒^b)" have already been tested.

The ^BEstimated^B time is a "best guess." It moves around a bit at
first, but settles down when some of the guesswork is removed
from the guess.
'
This unique and very useful feature lets MIS directors and
PC coordinators restrict non-technical users from making
corrections with Norton Disk Doctor. You can disable all
modifications to critical system areas and you can have the
Doctor display a custom message instructing the user in how
to proceed.

To enable this feature (and disable error corrections):
  * Check the ^B[ ] Prompt with Custom Message^b check box.
  * Press Tab to move into the message box, and type your
    custom message. For instance, you might type:

  █▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀█  Press F2 to
  █                          █  change text
  █      Contact Dan in      █  attribute.
  █   PC Wetware Services    █
  █      Extension ^B1123^B      █  Current attribute
  █                          █  is ^bBold^b.
  █ ^bDO NOT USE THIS COMPUTER^b █     
  █ ^buntil this problem has^b   █ (this changes as you press ^BF2^B)
  █ ^bbeen resolved!_^b          █
  █                          █
  ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀

You can dress up your message with certain color attributes:
Normal, Bold, Reverse, and Underline. Just press ^BF2^B to cycle
through the choices before typing the text.

Finally, press Tab to move to the ^b[OK]^b button and press Enter.
Remember to select ^hSave Options^h in the Disk Doctor Options
dialog.

  ^bTip:^b If you want to see what your message will look like in
  action, just diagnose a floppy disk in a diskette drive
  and open the drive door during the system diagnosis.

This feature does not affect the action during the surface
scan testing, but you can disable corrections there using the
^hTests to Skip^h dialog box (and save your setup).
Use Tab to move from check box to check box. Press ^BSpacebar^B to
toggle an option on or off. Select ^B[OK]^B (or press ^BEnter^B) when
satisfied with your settings or ^BEsc^B to cancel.

^BSkip Partition Tests^B tells Norton Disk Doctor not to perform
  its early test on the ^hhard disk partition^h table. Disk Doctor
  recognizes all standard partitioning setups, but this lets you
  skip the tests if you have an incompatible system.

^BSkip CMOS Tests^B tells Norton Disk Doctor not to perform its
  early verification of the ^hCMOS^h configuration settings in
  this computer. This is needed only if your computer uses a
  non-standard format for its CMOS configuration record.

^BSkip Surface Tests^B causes Norton Disk Doctor to skip the time-
  consuming surface-testing portion of its diagnosis. With this
  box checked, Disk Doctor tests only the system areas of any
  disk.

^BOnly 1 Hard Disk^B causes Norton Disk Doctor to test only the
  first hard disk on your system. This overrides the rare case
  where a system reports two physical hard drives when only one
  is actually installed. 

If you want these settings to become the defaults, remember to
^hSave Options^h in the Disk Doctor Options dialog.
This option immediately saves all option settings you have
specified through the ^bDisk Doctor Options^b dialog and its
sub-dialogs.

All saved options become the default for the current session
and subsequent sessions with the Doctor. Of course, you can
override default option settings for one session by selecting
options without saving them.

When NDD encounters a disk problem, it normally presents a
dialog such as:
       █▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀█

       █     Do you wish to correct this problem?     █
       █                                              █
       █                                              █
       █    [   Yes    ] [    No    ] [  Cancel  ]    █
       █                                              █
       ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀

Read the ^bDescription^b and ^bRecommendation^b carefully. In most
cases the correct action is to fix the problem (select ^b[Yes]^b),
but you can forego the correction by selecting ^B[No]^B or cancel
the rest of the testing by pressing ^BEsc^B or selecting ^B[Cancel]^B.

The Doctor may ask if you want to create an ^hUndo Information^h
file and where to save it. It is always best to hedge your
bets by creating the Undo file. It is normally a wise move to
save the changes to a disk other than the one being tested.

 ^bNote^b: If a ^hCustom Message^h has been enabled via the
  Options dialog, the message will be different and the user
  will have only one choice──to "Cancel."
The Doctor has located an Undo file on the chosen disk.

  ^BWarning:^B Examine the ^bdate and time^b shown in the dialog. If
  it does not match your expectations, do not proceed with the
  undo operation.

The Undo file contains ALL CORRECTIONS made to ALL DISKS
during the specified session. You cannot selectively undo a
single change or pick a single disk.

Select ^b[Yes]^b to proceed with the undo or press ^BEsc^B to cancel.
When files are open, it is very likely that Norton Disk Doctor
will report errors that don't really exist. In this situation
we recommend you skip testing on the drive, and then find out
why files are open. For example, some TSR's and DOS Shell
programs keep files open at all times. For best results, you
should exit to the DOS prompt, unload all TSR's, and try 
running Norton Disk Doctor again.

For the technically inclined...
───────────────────────────────
When files are opened, certain "bookkeeping" information is
copied from disk into memory. As new data is added on the end
of a file, only the bookkeeping information in memory gets
updated. The disk is not updated until the file is closed.

Norton Disk Doctor can only diagnose problems using information
stored on the disk. When the information on disk is no longer
current with the information kept in memory, Disk Doctor
reports an error, usually Lost Clusters. This "error" does not
really exist -- everything will be okay as soon as the files
are closed.
Each hard disk contains a Partition Table at the beginning
of the disk. It describes how the drive has been divided,
or "partitioned," into one or more drives, and how the drives
are set up for access by one or more disk operating systems.
The FAT (File Allocation Table) is a table of information in the
system area of each disk. It identifies the use of each cluster
on the disk as free, belonging to a file, or bad (unusable).

A cluster is the basic storage allocation unit for files.
Files are written to disk in pieces called clusters, which are
the basic storage allocation units for files.

Lost clusters contain valid data but cannot be linked up with
any known file. However, lost clusters ^Busually^B contain nothing
of value. They may occur, for example, because an application
was not exited gracefully: You turned off the power without
properly quitting and the application had files open.
Complimentary Metal Oxide Semiconductor (CMOS): A battery-powered
chip in 80286 (and more advanced) computers that preserves basic
data about the system's hardware.

System setup information is stored in this CMOS memory so it will
be preserved while power is turned off. 8088-based PC/XTs do not
have this feature.
