Thanks Mikkel. Not for the reason you are thinking. For performance reasons it helps to have each PATA disk on its own controller. You should always check the jumpers on the drives. Some need to be master even if there is only one drive on the cable. Others are OK being set to cable select if they are the only drive. And when there are two on a cable you want them both to be cable select or one master and one slave.
