Summary: HD floppies in a 360K drive


The coercivity of the magnetic material on HD floppies is greater
than the material used for 360K diskettes.  The above fact prevents
a 360K drive from writing on them.

The situation is analogous to trying to record on a metal cassette
tape in a standard tape recorder.

Unfortunately, it still doesn't explain why HD disks don't have hub
rings!!
