I use a 300gb U320 drive on my csppc. I have an active terminator on both ends of the cable. I have a bunch of scsi1/2 devices too including cdrom etc. The main drive runs at full speed. Only problem I had was when I had two U320 drives and I had to remove the active terminator from one end to get it to work correctly with both (although this was only the case with a certain combination of drives). No idea why. The csppc termination stuff seems to be quite random sometimes ;-)
