- DSKWATCH.COM - A program that reports on all disk i/o errors.
- Notes by Bernie Eisenberg, 213/391-0487. 9/15/85.
-
- This program was published in PC Magazine. The assembly language
- version was used, but it did not assemble correctly with the Microsoft
- MASM (presumably, it did assemble with IBM's macro assembler). So, I
- made the corrections and this is the version that you have now.
-
- To use it, just put the following line in your autoexec.bat file:
-
- dskwatch
-
- If you have set your path correctly, or if the .com file resides in the
- root directory, the program will load and become memory resident.
-
- The program will report each and every i/o error that the bios
- encounters, while not interfering with normal DOS error reporting. It
- will report on errors in the upper right corner of your screen. The
- following errors are reported:
-
- Message What the Message Means
- ------- ----------------------
-
- 1. No response drive probably empty
- 2. Failed seek
- 3. NEC error
- 4. Bad CRC seen intermittant error; during FORMAT, the sector will
- be marked 'bad' by DOS
- 5. DMA overrun NEC has to wait until the PC bus is available
- 6. Impos sector NEC received request to i/o a non-existant sector
- 7. No addr mark usually when NEC tries to read unformatted disk, or
- when a foreign disk's tracks do not entirely coincide
- 8. W. protected write protected disk
- 9. Err unknown bad error, since NEC doesn't even know what happened
-
- NEC is the i/o controller chip used in the PC. Good Luck.
