I've got one simple idea for you to try. You probably did this already 
but you don't say so explicitly.

The 80 conductor cables are color coded. Blue connector goes to the 
motherboard, black connector to the master drive, grey connector to the 
slave drive.

Did you plug the cable in the right way?
