If I took two hard drives with operating systems and installed them on the same IDE cable as masters. Then installed a switch that alternated power between each drive so that in position A only drive 1 had power, in position B, only drive 2 had power. Would this give me a dual bootable system? I have seen other switching devices that changed the jumpers externally, but this still means the second drive is spinning and accessible. I like the idea of having the unused drive powered down and out of the loop. Make sense?
