The motherboard end of an 80 conductor cable is special because one of the positions in the socket connector is disconnected from the cable so that the host can tell which kind of cable is attached. If the cable is plugged in backwards and the middle connector is plugged into a drive, the host thinks the cable is a low speed 40 conductor cable. Another possible problem is that the slave drive cannot correctly pass the results of its power-on-self-test to the master drive.
