About 6 months ago I started having SCSI disk problems on my
Supermicro P6DGU. It would take the machine 2-3 minutes to recognize
the disk at all on cold startup, then it would run fine. Then it took
longer and longer, then I started getting disk errors. I figured the
disk was bad and old, so I swapped it out for an identical spare. Same
issues. Hmmm. I figured something else was wrong, so I completely
traded disks as a test. Not even using the same technology (the old
Maxtor Atlas 10K was a U160, the new Quantum can do U320 although of
course the motherboard will only drive it at U160).
But I'm still having problems, and in fact they're getting worse. More
random errors, longer to start up from power-off, etc. I can't believe
3 different drives are all bad, so I'm wondering if this 5-year-old SM
motherboard is giving up the ghost as far as SCSI is concerned. But
I'm at a loss to even begin to debug this...short of buying a
replacement motherboard on Ebay and swapping the current one out.
Ideas? Similar experiences? Thoughts on approaching this? I've like
the P6DGU (this is destined for a server application, eventually) but
at this point maybe I should just junk it and get another mobo?

PS: The disk is attached directly to the SCSI connector on the
motherboard, using the SM-supplied cable with an active terminator
built in). It's the only device on the SCSI chain. I'm running a
single PIII-1GHZ coppermine; the second CPU slot has a terminator in
it. OS is Win98SE (yea, it's old, sue me). Not overclocked.
PPS: It's not termination. The bus is terminated with an active
terminator and was running fine before this with the same
cables/hardware.)
