ZP My 68 pin mobo connector is Ultra Wide and the hdd is Ultra2 Wide and is operating at Ultra SCSI performance levels (40 MBytes/sec). This arrangement has been OK'd by Quantum support. I believe one can put an active terminator or a passive terminator on the end of the cable. Yes...you can.. but when I do that I get a BSOD during bootup. Connecting a non-Ultra2 peripheral to the Ultra2 SCSI connector forces the Ultra2 SCSI segment and any attached peripherals to drop down to Ultra SCSI performance This chain is already at Ultra performance level because of the Ultra mobo connector. So if I add the 50 pin CD-R to this chain I'm thinking maybe the hdd performance might drop down to the level of the CD-R. This is still a concern even though you did not see any documentation one way or the other. Since your existing setup does not seem to be correct wrt termination of your harddrive it is hard to predict how termination should be set if you add a new device I agree.. the termination status of this chain has stumped even the SCSI Pro tech. Since it has been operating flawlessly in its current state I have avoided any further attempts to figure it out. I'll think a bit more on the option to add the CD_R. A functional and terminated CD-r on the end of that chain is appealing except for the possibility of lowering the performance of the hdd. I'm not sure which of the three possible Cablemaker adapters yet ( have to crack my case to see male/female requirements) but the most expensive is $30.. that would be the cost to experiment.
