- %GENERAL
- Damnspot looks for bad sectors on a disk and tries to do something intelligent
- with them. Under certain circumstances it may write data to unused blocks on
- the disk but will not effectively change the disk (alter the directory)
- unless you give explicit approval at the termination of the scan.
-
- At the moment you should press Q if you wish to abort the program.
-
- Otherwise be sure that the disk to be checked is mounted and enter a letter
- specifying the disk drive it is on (e.g. B)
- &
-
- %SYSTEM AREA
- Some computers format the system area differently than the rest of the disk.
- Also, what appears to DAMNSPOT as system area may in fact be a number of
- tracks reserved for other reasons, such as the trick used in faking several
- logical disks on a single physical disk.
-
- This option allows you to dispense with system area checking.
- &
-
- %BAD BLOCK
- The choices permitted are as follows:
-
- <H> Generate this help message
-
- <I> Ignore the bad block leaving it in its file. Neither replace it nor cover
- it (add it to [UNUSED].BAD).
-
- <S> Substitute a readable block for the bad one. The block substituted will
- contain a pattern of lines of the form < OUT OUT ... OUT >. This does
- not repair your file - it simply ensures that it will be editable (if it
- was a text file) and shows clearly which portions have been lost.
-
- <R> Try again to recover the data. If the retry succeeds Damnspot will
- immediately tuck the data away in an unused block on disk. If you later
- give directory update authorization this good block will replace the bad
- one, therby fixing the file.
-
- <Q> Quit scanning the disk.

- %CATASTROPHE
- #G ===> YOU HAVE A PROBLEM <===
-
- A hardware write error has occurred while trying to rewrite the directory to
- your disk. Unless something is done right away any files on the disk will be
- effectively lost since the old directory has probably been trashed.
-
- A retry can be attempted either on the current drive or after moving the disk
- to another drive.
-
- If a retry fails, there is still hope of recovering all or most of the disk's
- information, based on the fact that a (possibly modified) version of the
- directory still exists in memory.
-
- Other options include sending the directory information to a file or device,
- and copying the trouble disk to another similar disk using the directory from
- memory and data from the user area of the disk.
- &
-
- %RETRY UPDATE
- Retry writing the directory to the current drive. This is worth a try or two
- if the information on the disk is valuable. If it is worthless just reformat
- the disk or throw it away.
- &
-
- %NEW DRIVE UPDATE
- Retry writing the directory but after first moving the trouble disk to a NEW
- drive. That might make the difference.
- &
-
- %COPY DISK
- Copy the directory (from memory) and the user area of the trouble disk to
- another disk. Please note the following:
-
- - Bad blocks will not be copied
-
- - This is a disk image copy - any information on the target disk will be
- destroyed!
- &
-
- %QUIT UPDATE
- Quit this disk. No further actions will take place on it, although you will
- be warned if it has not been successfully updated.
- &
-
- %SWITCH DRIVES
- It is possible that you will be able to update the disk directory if you place
- the problem disk into another drive and then write the directory.
-
- CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION
-
- If you specify another drive you MUST place the problem disk currently in
- drive #D: into it. If you specify a drive containing some other disk that disk
- will be ==> CLOBBERED <==
- &
-
- %FILE OUTPUT
- This option allows you to write the modified directory information to a file
- in either Ascii or Binary form. Ascii form means in a form that can be
- displayed on the screen or on a printer. Binary form means that the contents
- of the file will be identical byte for byte with the contents of the disk
- directory - or at least with what they would have been if the normal updating
- had succeeded.
-
- You may also send the directory contents to the terminal or printer in Ascii
- form - think of these devices as special forms of Ascii files. (Or think of
- Ascii files as being special forms of printer - whatever helps.)
-
- Saving the directory information in this way is not much use unless you are
- capable of using the information in it to fix the disk in question. See DS.DOC
- for some hints on this.
-
- DO NOT TRY TO SEND THIS FILE TO THE CORRUPT DISK - USE A GOOD ONE !!!
- &
-
- %UPDATE OPTIONS
- The Option menu will tell you what your possible actions are at this time, and
- provide detailed help on each.
-
- If no bad blocks have been detected, you probably just want to Quit. You may
- also wish to quit if you would rather that DAMNSPOT do nothing about errors it
- has found.
-
- If you go to the options menu, you will be allowed to Update the directory to
- reflect changes, save Directory information to a file or device, or copy the
- disk in its new form (using the updated directory information in memory) to
- another disk.
-
- The Summary option redisplays the disk status summary.
- &
-
- %FLAKY BLOCKS
- Blocks on which Damnspot dwelt for an appreciable time are flaky. If you saw
- the same block number remain on the screen for a second or more, its future
- integrity is questionable. If it does not now have valuable contents, you may
- wish to force it into the bad blocks file to prevent later problems.
-
- If you specify such a block, Damnspot will first check to see whether it is
- currently in a file, and request confirmation if so.
-
- Block numbers to be forced bad should be specified in hexadecimal without any
- other special characters. I.e. say B3 rather than $B3 or B3H.
