As I [mis]understand it, this is NEVER supposed to happen, unless you have a really fancy hard disk controller with multiprocessing capabilities that can access two disks at once. Sounds to me like you have a drive address conflict. Some of the ribbon cables have a portion of them twisted to change the effective address. In this case, the DIP-switches on both drives should be set to the same physical disk address. If your ribbon cable (the wide one going to both disk drives) does not have this twist in it, you must either put it in there, or change the physical address of one of the drives by setting a DIP-switch or jumper. Warning: I HAVE been wrong before... Good luck!
