David Stanhope suggested that I'd get a 80-wire IDE cable.  Yesterday I
did, but it didn't seem to help at all.

Changing the IBM to be a master and the Seagate to be a slave didn't
help.

Removing the Seagate altogether didn't help, either!

I get CRC errors every time I do

"dd if=/dev/rwd0e of=/dev/null bs=1M count=100"

and the driver degrades to PIO4 mode.

I'm using a Soyo SY5-EHM motherboard and it has worked just fine this far.
With the IBM, something does not work right.

Manuel Bouyer said the CRC errors happen between the IDE drive and the
motherboard, so it shouldn't be a driver issue.

Am I the only one who's seen problems like this?
