I would figure it would be cheaper to put a strip of tape over the notch (if the sliding black thingy is missing) than to buy a whole new controller. On a 5.25", it's the opposite. You'll want to cut a notch out to write to a disk. Is there a controller that would bypass this? I don't think so (could be wrong though). I would think it would be easier to modify the drive than the controller. I still say a piece of tape is easiest. -tony
