Tape closed the disk hole/notch that indicates HD media. Why copy sector 
by sector? That should not be necessary.

BACKUP may seem to use tracks but it actually divides memory into tracks 
and then fills that memory sector by sector. The only Coco command that 
uses tracks is DSKINI where a track is written in one pass. All other 
commands are sector chunks.
