Things I have found useful with this sort of problem:
1) Try changing the state of the Cable Select jumper. Some drives are
funny and want it on even when you're not using Cable Select.
2) Take the CD-ROM off, and try the drive as the sole device on the
cable.
3) Make sure there isn't a mismatch between the methods the drive
connector and cable connector use for polarisation, which has led you
to plug it in upside down without any obvious physical difficulty.
2) is probably the most likely.
Can you try taking the laptop apart and running both HDs in that with
a cable out of the desktop?
