- Here's the deal: I borrowed a 52meg external hard drive so I could back
- my hard drive up to it.
-
- I hook it up, fire it up with my system, and everything works
- fine. For a while. But pretty soon, as I'm copying files from my HD, I start
- getting a few disk errors: read, write, key not set, bad header, all sorts.
- So I try using my second partition, and get more of the same errors.
-
- I use QBTools to fix the problems, and 30 seconds after exiting the program,
- two dozen more disk errors appear! Even wierder, my floppy drives are doing
- the same thing!! If I try to format a floppy, it breaks with a read/write
- error message. Before long, both my floppies, both my HD partitions, and the
- borrowed HD are completely worthless. They've all been invalidated, so I
- can't write to them, and 80% of the files I try to access either report some
- sort of disk error, or crash the system.
-
- I tried reformatting the borrowed drive; same thing happened all over
- again as soon as I rebooted. I finally just gave up and disconnected the
- drive, then spent an hour with QBtools trying to fix all the damage to mine.
- Didn't lose anything, tho.
- Any ideas on why this would happen?
-
- VITAL STATISTICS:
-
- A500 with 5 megs ram
- Supra SCSI interface (the OLD kind, w/separate i'face and HD cases)
- Quantum 85 Meg HD, two partitions (20 and 65)
- Seagate 52meg HD, ST157 I think. (That's the borrowed one).
-
- The Quantum is connected to the Supra interface, and the Seagate
- is daisy-chained onto the back of the Quantum.
-
- Not knowing diddly-squat about terminator packs, I didn't mess with
- them. Could that be causing this?
-
- Thanks for any help you can provide!!!
