Yeah. I suspect that you are right. I have an A2000HD. The A2091 now
has a Quantum 40S hard drive and a 3M MCD tape drive. I changed
reselection last evening and putz around with the tape drive for several
hours. My original problem was that often, not always, the backup would
hang with the SCSI light (aka HARD DISK light) on the front panel lit
continuously.
After changing reselection the backups still fail, at least as
frequently. Now, however, the process hangs with the light ON or OFF.
Darn. I am quite irritated with the problem. But I got the tape drive for
$50 so I'm not out too much.
What role does addressing and termination play in the SCSI scheme. The
Quantum is at address 6 and the tape at 3. Originally, months ago, the
tape was on the cable before the Quantum and unterinated as I understand it
should be. I switched the cable and terminations around so that now the
Quantum is in the middle, i.e. between the A2091 and the tape drive. I
have not noticed any degradation in hard drive performance nor have I had
any problems that would tilt me towards doubting the hard disk. But the
problem persists.
Gack! It's probably some really simple idiocy in the scsi.device
driver; but, I haven't the accumen to know what or how to go about fixing
it.
