Huh. I'm not so certain about that. I had the same problem on Monday
with some very old exabyte that I wanted to use because nobody else
wants it. `echo "scsi add-single-device 0 0 5 0" > /proc/scsi/scsi'
brought the shell-builtin echo to D-state, no further reaction, no
blocked drives, until after rebooting - scsi dead. Since I suspected
a cable problem I didn't follow it any further, but it worked a week
ago with the same hardware, except that I couldn't do non-rewinding
operation, which sucks universes.

This stuff here sucks badly, so I won't continue testing with
it any more. The material is just too old, and you never figure out
where the problems are. It only pays if you know it works on different
soft/hardware.

Ah, btw, it is an 53c810a, rev 0x12, 2.0.35-alan-pre5.
