[Coco] FD-500 Floppy Drive

All of the disks I'm using have the index hole.

My vague recollection is that Commodore disks might not have an index hole,
needed on the CoCo only for formatting.  This is a hole adjacent to
the center of the disk, both in the disk itself and in the envelope
containing it.  You can make one with a paper punch if you're careful.
