Please provide hardware details.  It's likely that those two drives won't work
on the same controller.  I've heard rumors of older drives not playing nice
with newer drives on the same controller.  Are you sure the first drive works
at all?

Don't know of any.  But you might want to scan the ATA/IDE section of your BIOS
to see if there's anything that might be useful.  Perhaps if you can force it
to a slower speed (ATA33 for example) it would work ... but I'm just guessing.
