I have a computer with 3 hd and a burner. I have it set up so that 2 hd are on one cable and a hd and the burner are on the other. Problem is that the secondary IDE won't detect both the hd and the burner. It will detect one or the other, or neither. If they are both plugged in (hd master, cdrw slave) neither drive shows up. If the cdrw is master and hd slave then the cdrw shows up but not the hd. And if one or the other is plugged in it will detect which ever is plugged in. Why won't it detect both drives...? I have checked and rechecked to make sure they are in the proper order and the jumpers match.
