Hi...
I'm seeing a problem using Ultra wide SCSI with a pair of 9G Viking II
drives.
The symptoms are read timeouts and bus resets. And inevitable data
corruption.
The problem goes away if I change the negotiation to Fast SCSI (20MB/s).
I've tried a different 958, different cable and different drives. So I
suspect the motherboard or the driver at this stage. Can anyone offer any
clues?
The motherboard is... I've forgotten. Some recent genuine Intel 440BX
chipset thing with a Celeron 333 slot 1 CPU and 224 meg of RAM.
