Let's make this easy.

Use a 80 wire ide ribbon cable only. You won't have problems with
cross-talk, or random RF riding the cable.
On one end, colored blue, connects to the motherboard or pci interface ide
adapter board. The middle is gray, the slave is meant to go there. The end
is black, the master is meant to go there.

If you use cable select, both devices on the ide ribbon cable must use it.
Master will be on the end, slave in the middle.

If there's special settings, go to the hard drive maker's website armed with
the model number printed on top of the hard drive. One special setting
recently introduced a couple of years ago is the 32GB capacity jumper for
PCs that have trouble with hard drives bigger than that.

You may consider setting up primary master/slave as WD/DVD, and secondary
master/primary as Seagate/DVD.
