When equpment such as EIDE drives which are allegedly compatible with each
other turn out not to be so, the only way may be to use the standard
technitian's method for fault isolation. start swapping parts of your system.
Find a friend with a standard 4x drive (I used Toshiba and Hitachi 4x drives
which are OK), who will be glad to swap it for an 8x drive for a few days,
then you can make sure it's really the drive and not your motherboard.
If this fails, try testing the drive on nanother linux box (finding a friend
with a linux box is a bit tough unfortunately).

I had a Toshiba XM5302B drive, which:
1. worked perfectly under Linux (data only).
2. Locked up sometimes when playing audio disks on DOS
3. locked up when reading CD's under NT 3.51.

the only way I could isolate the problem was by swapping this drive with my
brother's Hitachi drive. It turned out to be a drive problem (I still don't
know if the specific drive is defective, or if it's a firmware problem in the
drive).

I could not find the solution without swapping parts of my system.

But then, I find myself opening my machine at least once a week for various
reasons, so for me swapping a drive is trivial. It may not be the solution for
you (even though if you are playing the linux, there are good chances you can
do this as well...).
