Forgive me, I'm rather ignorant of SCSI hardware.All that I have is a
cable (appears
to be good quality, came with motherboard) about 60 centimeters long going

Hm. As a point of comparison, I use a similar system to yours (full SCSI,
though, no IDE) and I can copy a 100MB file from disk-to-disk, or on the
same disk, in around 13 seconds. Where are you copying to the SCSI drive
from - the same drive, an IDE disk, CDROM? If IDE, what are its
particulars?

Hi.
Do you get messages like the ones below in /var/log/messages?
sym53c875-0-<0,0>: QUEUE FULL! 8 busy, 7 disconnected CCBs
sym53c875-0-<0,0>: tagged command queue depth set to 7
In fact, do you get any messages in your log files that look like they
might be related?
