I've just finished configuring a SCSI chain on my CSPPC much like the one
you're working with. The layout looks right, but the one thing that I
haven't seen mentioned is term power. Make sure it's supplied by one of the
drives, preferably ones closest to the ends of the chain if you have a
choice. The best little tool you can have for SCSI is a terminator with an
LED to verify that the terminator is working and has proper termination
power supplied. Also, make sure you've got the CD-ROM set to 8-bit. It won't
work in 16-bit mode.
Some HDs will claim they have active termination available via jumper, but
I've run across a few drives that don't terminate even with the jumper set.
Investing in a couple of good active terminators may help prevent problems
down the road.
Here's a great SCSI reference page:
SCSI Terminators and Standards.
Let me know if you have any other questions. I'll do what I can to help.
