Now what confuses me is this: WHY is stepping a track a requirement to update the signal?? Surely the drive detects it by some sort of mechanical or perhaps optic switch which is activated by the actual disk insertion -- so why not update the signal instantly? Is there supposed to be some value to it? Is there some technical obstacle, or was there? Was it just the semantics of whatever drive it was convenient to use? I don't get it. Deven -- Deven T.
