I'm thinking of things like drive door being open, drive being read only, etc. Along the same lines, I'd like to put together a disk backup utility that would not let the user format the source disk, and then wait to copy the blank one onto it. If the disk has been erased with a tape eraser, there is no directory to check for. I'm looking for these to be truly bullet proof, if there is ANY chance of error, the user may be better off without them. (All this is targeted for a Zenith Z89 with 2.2.03 CPM, if that matters) Many Thanks in Advance Don Taylor tektronix!tekig1!dont
