it may be a few my experience with two Maxtor drives (one 345M
from a few months ago and a 1280M from a few weeks ago), they seem to
coexist much better with western digital if they are set to be master (in
fact, my 345M won't even work with my old western digital 120M). If you
are using hdparm to set multi sector reads, etc, you might want to try
leaving the setting at the default and see if that clears the problem
up. Please mail me directly if you have any problems, or if I am
completely off base and misunderstood your problem...I have had a total
of 5 different IDE drives and a 4x cd-rom in my system (not at the same
time, unfortunately ;) ), and have become quite comfortable with
configuring drives to work with each other, on one and two IDE channels.
