- DTST - Yet another disk tester v2.0 01-May-90
- ============================== (C) 1990 Samuel H. Smith
-
- DTST is a small utility that is used to check out your hard disks. It
- has the special ability to report "slow" sectors. These are sectors
- that read properly, but often require retries. I feel that such sectors
- are on the verge of failure and should quickly be locked out before they
- cause any harm.
-
- DTST consults your FAT and reports if clusters are already marked bad.
- You can use another disk utility (such as Norton's NU) to locate any
- files using the questionable sectors. Copy the files to a safe place
- and then use "DT" to mark the blocks as "bad". This will prevent real
- trouble before it happens.
-
- Use this at your own risk! I am including source code so you can verify
- that it has not been hacked.

- ----------------
-
- 15-feb-88 v1.0

-
- 21-feb-88 v1.1
- Added two optional parameters to specify the first and last
- sector number to test.
-
- 21-may-88 v1.2
- Changed scanning direction. Consults boot record for information
- needed to calculate cluster numbers.
-
- 23-may-88 v1.3
- Fixed the 'slow sector' message, which was broken in the 21-may version.
- Also reduced display activity during testing.
-
- 16-jun-88 v1.4
- The FAT is now loaded to determine clusters which are already marked
- as bad. Added READ/WRITE test. Initial SourceWare release.
-
- 26-jun-88 v1.5
- Directed the non-error track by track status messages to the display
- regardless of where standard output has been redirected. This removes
- clutter from a logfile if you are running DTST in a batch with output
