- HDCHECK version 1.3 07/29/89
-
- I felt compelled to update HDCHECK after finding the maddening bug
- that disabled auto-boot. It was simple to repair (rerun the auto-boot
- setup program), but frustrating for anyone using the boot sector
- update function. My apologies for any inconvenience or tense moments.
-
- The program fix was also surprisingly simple - a call to the Bios
- function Protobt() to recalculate the checksum as suggested by Kent
- Schumacher. The checksum was discussed in an article by David Small
- in the May 1989 issue of Start. The sum of the bytes (I assume bytes)
- in the boot sector must equal 1234 hex for the drive to be considered
- bootable with the last two bytes used to make it come out to exactly
- $1234. David neglected to say how it was calculated. After I spent too
- much time trying to calculate it myself, I took a look at Protobt().
- It worked the first time.
-
- This version also includes interface improvements and other minor
- fixes.
-
- - The transfer test will now work if the boot sector information is
- incomplete.
-
- - Partition (drive) and logical partition sector number will now be
- included with the sector information displayed during a number
- of the tests. Previously this was only included if the boot
- sector information was complete.
-
- - The TOS error number will now be included in file read error
- messages.
-
- - Using the RETURN key in response to input will now leave input
- fields unchanged.
-
- - Other simple improvements to make it more friendly.

- HDCHECK was written to deal with a rash of problems I had with my hard
- disk. I went through three hard drives and a DMA cable before things
- settled down. When I found that the Atari drive maker was using a
- picture show program to test my drive, I decided it was time to write
- a test program.
-
- The programs forte is checking-out failing drives on multi
- drive/controller configurations. Should work on any Atari ST or Mega.
- Future features may offer repair options. Except for the file scan
- feature the program currently deals with the drive physically and
- ignores the partition boot sector, FAT and directory structure. You
- should find most of the help you need with the program in the built in
- help screens. I know that takes room in the executable, but that way
- your DOCs won't get lost.
-
- Thanks to Supra for putting their low level hard disk routines in the
- public domain, the same ones used by David Small and Dan Moore with
- their Mega-Minute backup program.
