It's probably best to move everything onto the new disk if you can - HDs
tend
to die when they have a rival (assuming the new one is a good one, etc).

IIRC bitrate is allocated per channel, not per primary/secondary device,
so either should be equally fast. Wikipedia:

No, you will need to change /etc/fstab at least. I don't have a decent
link for this one, couldn't see anything on the LUG wiki.
Googling for answers may work better if you search for ATA instead of
IDE or EIDE because it's properer.
