You didnt say if the drive connectors or the motherboard end are polarised.

And that should happen with an 80 wire cable too.

Most likely you arent putting the connector in the right way around with the
80 wire cables, or its some weird effect with that particular motherboard.

The motherboard does decide if the 80 wire cable is a cable
select cable from what it can see of the cable, its possible
that that detection has now failed but thats not very likely at all.

Are the drives jumpered for cable select ?  I guess its possible
that they arent and someone had to kludge around a failure of
the bios to detect the drive initially and that kludge got bypassed
with the attempt to test a different drive or something.
