	While it is true that every floppy disk that I know of has a
hole which can be used to tell where the first sector starts, it is not
true that all disk drives use this hole. Apple drives, in particular,
are completely soft sectored. All sector information is written on the
disk by a formatting program. The drive does NOT contain circuitry to sense
the hole in the disk. (A penny saved is a penny more profit).
