I have an adaptec 2940U2W scsi controller, installed in a PC
which is used periodically.
When installed, it worked fine (and the devices hanging off it also).
The last time I booted (and since) it failed to see any devices
on the bus. I've checked the actual devices on another PC, and
they work fine. I've also moved the controller to another PC
and the problem is the same.
The devices in question are a hard disk, and a dat drive, both external.
The devices get moved periodically (say monthly) to other
computers. But they work fine on the other computers.
Any ideas ?
