The drive that was reliable will probably be unreliable because the
termination is then incorrect. Only the drive at the end of the cable should
be terminated. Swapping the drives would also have no effect as one is
jumpered as 0 and the other as 1. It is not like the PC where both are
jumpered the same (hence the twist in the cable).
