I can confirm the exact same problem on both a Pentium and a PentiumII
1.4 and 1.4C with a disk of the following kind:

wd2 at pciide0 channel 0 drive 1: <ST51080A>
wd2: drive supports 32-sector pio transfers, lba addressing                  
wd2: 1033MB, 2100 cyl, 16 head, 63 sec, 512 bytes/sect x 2116800 sectors     
wd2: 32-bits data port
wd2: drive supports PIO mode 4, DMA mode 2

I've been meaning to investigate this problem for a while already, but
can't do anything since I've loaned the disk a friend of mine (sneaky,
eh?).

I've noticed that this problem does not occur with wdc (or perhaps I've
just been in luck), so using wdc instead of pciide should help in using
the disk until the problem gets fixed.

When you get a 'hard error' it's tilt-time.
