When I called adaptec tech support, the person *kept* asking if I
was using external devices. I then saw this post and understood why.
I don't have anything external, yet I still have problems.
1542c ----- Q P105s ----- Q PD210s ----- Archive Viper
ID#7 ID#0 ID#1 ID#2
the 1542c and the archive viper have termination on. Turning it
off at either end has no effect, turning it off it both ends
makes nothing work. (surprise.)
The problems *only* show up under 386bsd and only *affect* my two
Quantum hard drives, the tape appears to work fine. One Quantum
gets trashed data and the other won't even newfs. As recommended
by the adaptec tech support person, I low-level formatted them
both but still have the same problems.
Last night I downloaded a program from the Adaptec BBS that can
set the bus on/off times. I twiddled them all around an it had
NO effect.
Given the symptoms, any tech support person is naturally going
to point their finger at the SCSI software in 386bsd. That is
about how I feel now too.
I'm really no sure what to do next...
