This message was posted a while back.
As with many of the problems posted here, there have been many solutions
suggested.
This one popped back into my mind recently when I was helping a friend with a
PowerWave (excellent unit btw) resolve a problem with his CDROM working
intermittently.
In his case, a replacement CDROM had been installed which worked fine at
times and not at others.
The culprit in that case was a jumper installed on the 'terminate' posts of
the CDROM,
which device was not the last on the chain. Removing the jumper cleared up
all problems
with the CDROM not mounting consistently.
SCSI chains are notorious for weird problems with termination , and its
worthwhile, when
a problem occurs with any SCSI device, to check address and termination issues.
Cheers...Michael
