I've got a GA-K8NSC-939 running 5.4-R (i386) with two 80GB using
UDMA100 that I've run pretty hard occasionally with dump/restore, diff
-r kind of operations, with no problems.  I ran 5.4-R (amd64) lightly
for a few days without noticing disk problems.

You said one of your disks was a slave. I've read rumors that that's
a bad thing if its master is a CDROM, but I'd think it should just
run slower than it's capable of.
