- DISK RESCUE
- -----------
-
- Disk rescue is a diskette recovery program which attempts to save the contents
- of a diskette, which normally is partially unreadable under DOS. I wrote
- DISK RESCUE originally 1987 and put it into the public domain as DISK
- RESURRECTOR (I know, nobody knows this program). I use DISK RESCUE quite often
- on my machine, as I use a lot of diskettes written to and formatted on other
- machines. It also proves quite useful on low density drives, when trying to
- work with diskettes originating from high density drives (formatted as low
- density diskettes, obviously ...).
-
- How does DISK RESCUE work ?
-
- DISK RESCUE first prompts you for the drive, where the diskette to be recovered
- is located. If your computer only has one drive, the only options you will see
- at this point are to use this drive or to abort the program. It will then try
- to determine the type of diskette in this drive. If not even this is possible,
- well - then are pretty much at loss...
-
- It will then read the diskette a track at a time. Once it encounters a read
- error it starts processing the track sector by sector. Once a read error is
- encountered on a sector, it will reread this sector and process some recovery
- until the sector can finally be read. This may be up to 50 times - so be
- patient. If even after this time the sector can not be read, you may abort
- the program by pressing any key. You will be asked to verify your decision.
-
- Once all the sectors of a track have been read, DISK RESCUE will attempt to
- reformat that track, rewrite and reread it. It will continue to do so until
- all operations perform without problems. It may take several cycles until
- the track has been recovered.
-
- Once a disk has been fully recovered it is quite advisable to make a copy as
- soon as possible. The fact alone, that it had to be recovered is indicator
- alone, that you will soon reencounter some problems. If the recovery was
- completed successfully, this should work just fine.
-
- Note:
-
- During its operation DISK RESCUE needs access to the file RESCUE.EXE. It
- is not possible to start RESCUE and then continue operations without the
- program file.
-
- Also it is not advisable to abort the operation between formatting and
- rewriting tracks. It is possible to loose a full track in this way.
-
- DISK RESCUE is herby put into the public domain. No guarantees whatsoever are
- given on its performance or the suitability for a specific purpose.
