I've been meaning to revisit this thread, suggestion:

Remove the termination resistors and hook up an internal drive to test to see if your card is good.

If it's the other way around, attach an external device with termination.

If terminated devices on both ends (without the resistor packs on board) won't work, I'd be suspecting that the card is bad. :-/

I've got a good card with the proper terminators to test it for you.
