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).

  ^bTip:^b  Don't bother moving to the ^b[Cancel]^b button.
        Just press ^bEsc^b; it's exactly the same.

On monochrome displays, the highlighted
button has button arrows and looks like       ^B Next ^B

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
to ^Bdrop down^b its menu and ^bclick^b on the desired command. Or, you
can be very Mac-like and ^bdrag^b to ^bpull down^b the menu then release
the button on the desired command.

Disk Tools is a set of automated procedures that protect disk
data, simplify some technical operations, and recover from
certain types of data disasters. These are safe, totally
automated procedures, with plenty of safeguards. These tools
are designed for easy operation even by novice users.

^BTo use one of the Disk Tools:^B
 * Highlight the desired tool and press Enter.
 Or,
 * Click on the desired tool using a mouse.

   ^BTip:^B You should ^BCreate a Rescue Disk^B immediately,
   if you have not done so already!

^BThe Tools^B
^B────────────────────────────────────────────────────────────────^B
 ^hMake a Disk Bootable       ^h
 ^hRecover from DOS's Recover ^h
 ^hRevive a Defective Diskette^h
 ^hCreate a Rescue Disk       ^h
 ^hRestore Rescue Information ^h
This procedure takes all the necessary steps to make it
possible to use a disk as a DOS system or "boot" disk; that
is, after you use this tool, you can start your computer when
this diskette is in drive A:.

DOS's ^bSYS^b command is supposed to do this, but it often fails,
saying, "No room for system files." Disk Tools makes room
by physically moving the files that are causing the blockage.
Then it copies the system files correctly onto the disk
(including Command.Com). It can even adjust a hard disk
^hpartition table^h in case that got scrambled somehow.

  ^bNote^b: This procedure is 100% safe; it cannot harm a disk.

The first dialog asks which disk to make bootable. Use 
^B^B and ^B^B and press Enter, or just press the drive
ID letter. The rest of the action is automatic.
DOS's RECOVER command is dangerous ── its default operation
causes you to lose all of your subdirectories! The DOS 
manual suggests using RECOVER after you see a "sector
read error," but use the ^BNorton Disk Doctor^B instead to
heal that problem.

After using DOS's RECOVER, your root directory contains
files with names like ^bFILE0000.REC^b, and there are no
subdirectories. In that case, use this Disk Tool to clean up
the mess.

There is one other reason to use this tool. In the ^Bvery rare^B
case where your disk's directory gets scrambled, but the
^hFile Allocation Table^h is intact, this can rebuild the directory
(albeit with arbitrary filenames).

A dialog prompts you to select a disk. After that you'll get
two strong warnings (remember, this tool is needed very
rarely) and ^byou can back out by pressing^b ^BEsc^B ^bat any time^b
^bwithout harm^b, even after the disk map is displayed, right up
until the entire disk map is in colored in bold.

The rest of the action is automatic. The disk is analyzed
while showing a visual map of the disk data. At the end, the
directory of the chosen diskette will still contain names like
"FILE0000," but it will also contain subdirectory names and,
where possible, files will have their original filename
extensions.
When you see ^BBad sector reading drive A: Abort, Retry...^B, the
problem is often related to the "sector ID" marks BETWEEN the
sectors.

This tool rewrites the sector ID marks, without wiping the
data. In the case of a physical problem, say the disk is
scratched or if the disk came in contact with a magnet, this
tool will make a heroic effort to dig out whatever part of the
disk is readable.

Depending on the amount of un-revivable physical damage, you
should be able to see a directory on the disk and access it
normally.
This provides a simple way to tell DOS not to store data on
a particular part of a disk OR you can perform the reverse
operation ── tell DOS to go ahead and use an area that is
currently marked as "bad."

The Norton Disk Doctor or some other source may describe a
"disk error at cluster ^Bnnn^B" or similar message. You may use
this tool to put a special code in the File Allocation Table
(FAT) so that DOS will no longer use the defective part of the
disk. Actually, the Norton Disk Doctor will mark-and-move
automatically, but you may use this tool to mark manually some
clusters near the bad one; if one part of the disk is physically
damaged, nearby ones may eventually show intermittent problems.

^bThis is a very safe operation^b; the tool will check to see if a
file currently owns that cluster and, if so, it will move its
data to a different part of the disk. This is much safer and
easier, for example, than doing the work manually with Disk Edit
from the Norton Utilities. You cannot lose any data with this
tool.

Be sure to pick the right drive and (on floppy drives) put the
right diskette in place. The ^bMark Clusters^b dialog prompts for
a cluster number.

  Note: Input a ^Bcluster^B number, ^BNOT a sector^B number.

To change a "bad" cluster to be marked as "good", press ^BTab^B
and press the ^BSpacebar^B to set the correct button. You can
use this option to reverse any previous input mistake. The
now "good" cluster will become available for use by files.

Here's a simple insurance policy for hard-disk owners.

Three sets of information are critical to the well-being of
your hard disk. ^bWhen your system is healthy^b, use this tool to
make a record of the current settings. Then, if something bad
happens, you have a way to restore those known-to-be-good
settings.

  ^BCMOS Information^B: Includes the settings put in place when
     you run "Setup" on your AT-compatible computer.
     Especially critical are the "hard disk type" codes.
     Wrong values keep the disk from booting (among other
     problems).

  ^BPartition Information^B: Includes the "master boot record" (at
     side 0, cylinder 0, sector 1) and Partition Table for all
     hard disks. This is a description of the physical
     characteristics of each disk, how it has been divided up
     into DOS drives, and whether you have any other operating
     systems on the same disk. Wrong information in here will
     keep the disk from booting and/or make DOS unaware of its
     existence.

  ^BBoot Information^B: This is the DOS Boot Record. DOS depends
     on accurate information in this sector or it can't find
     the FAT, root directory, that spreadsheet, the payroll, or
     anything.

     ^bNote: ^bTo get a printed report of all the information
     saved here, use the ^hSystem Information^h report feature;
     it displays and prints out this same information, but in
     a form readable by people.

     ^bNote, too^b: You may wish to use the Norton ^hImage^h program
     as an added precaution; it saves additional DOS-specific
     information that changes often, such as your directory
     structures and so forth.

This tool is easy to use. Follow the prompts and, when asked,
select a floppy drive and insert a formatted diskette into the
floppy disk drive. 

  ^BCaution:^B You can specify any drive to hold the rescue files,
  but don't use a local hard drive. After all, how can you 
  restore the data from a drive you can't access. You can, 
  however, safely use a network drive to hold the rescue files.

Three files are created on the drive. If you use a floppy
diskette, write something like "Norton Rescue disk for Dan's 386"
or "Rob's 486 Rescue Disk" on the disk label and put the disk
away in a safe place. 

  ^bNote:^b Repeat this procedure each time you make a major
  configuration change, such as adding or removing a hard disk,
  installing a new version of DOS, etc.

If a virus or "Trojan Horse" program does some nasty business
on your hard disk, if the battery goes dead on your AT, or
if in moving your computer, the hard disk gets a bump on the
head and the Doctor can't fix it ── pull out the Rescue Disk,
and use the ^hRestore Rescue Diskette^h procedure in this Disk
Tools program. You'll probably need this disk once every two
or three years.

Use this tool when you can't access a hard disk and the
^hNorton Disk Doctor^h is unable to fix the problem.

This restores all (or selected parts) of the information saved
in a previous use of the ^hCreate Rescue Diskette^h procedure.

In the ^bRestore System from Rescue Disk^b dialog box, you can
decide which information to put back in place. By default, all
the options are unchecked.

To check an option, use ^B^B and ^B^B to move the cursor and press
^BSpacebar^B to toggle the option on. When satisfied with your
choices, press ^BEnter^B to continue. Press ^BEsc^B at any time to
back out.

  ^BPartition Tables^B: These can get messed up by unwise use of
     DOS's FDISK program. Or perhaps when you added a second
     hard disk, something happened to the partition information
     in the first disk.

  ^BBoot Records^B: These might get modified accidentally by DOS's
     SYS command. Uncheck this if you have installed a newer
     version of DOS since you created your Rescue Disk.

  ^BCMOS Information^B: This gets lost if the battery dies or gets
     removed for any length of time. The most common use of
     this tool is to uncheck the other two options and restore
     only the CMOS data.

A list of available drives is displayed. Select the drive that
contains the rescue files. If the selected drive is not a floppy
drive, a text box appears for you to enter the directory that
contains the rescue files.
Disk Tools needs to know with which disk drive you wish to work.

Use ^B^B and ^B^B to move the highlight and press ^BEnter^B -OR- as with
all similar "pick-a-drive" dialogs, just press a drive letter.

When performing an operation on a floppy disk drive, you will
get another prompt asking you to put the right diskette in the
drive. It's wise to look at the label on the diskette to make
sure it is the right one.
The partition table is a description of the physical
characteristics of each disk, how it has been divided up
into DOS drives, and whether you have any other operating
systems on the same disk. Wrong information in here will
keep the disk from booting and/or make DOS unaware of its
existence.
The file allocation table (FAT) is a table in the system area
of each disk that identifies the use of each cluster as free,
belonging to a file, or bad (unusable). A cluster is the basic
storage allocation unit for a disk (usually between 2K and 8K
in size). Note that disk space is allocated to files in whole
clusters.
System Information is a program contained in the Norton Desktop
that reports the operational status of your computer:

  * hardware
  * software
  * memory usage
  * network conditions
  * disk drives
  * benchmark comparisons to other computers 

To run System Information, type SYSINFO at the DOS prompt.
Image is a program contained in the Norton Desktop that
takes a snapshot of the system area of your disk.

^hUnFormat^h and ^hUnErase^h use this information to recover
from disk disasters.
UnFormat is a program contained in the Norton Desktop that lets
you recover from situations that may appear hopeless: damaged
disks or disks that have been reformatted accidentally.
UnErase is a program contained in the Norton Desktop that lets
you recover accidentally deleted or erased files.
Disk Doctor is a program contained in the Norton Desktop that
runs numerous test to determine the health of your disks, warns
you if it finds problems, and gives you the option to correct
them. The wise computer user runs Disk Doctor regularly to
prevent small problems from turning into large ones.
