The SCA adapter can plug into either a narrow cable or wide cable.
Hmm, here is what I have tested this drive on:
windows pc with adaptec 2940uw (uw)
- scsi bus resets
alphastation 200 with adaptec 2940uw (uw)
- what you saw
Just now I booted my AS200 with the hitachi disk plugged into the
onboard NCR controller (fast narrow). Here is what ensued:

So, is the the same kinda thing thats been happening on the adaptec's?
Think the drive has problems? I am wondering if I should RMA this
