3.5" HD diskettes are very MARGINAL in Apple 800K drives, with some
not working at all and some working for a few hours or days.

5.25" HD diskettes are ABSOLUTELY IMPOSSIBLE in a Disk ][,
because the media difference is much greater, and the Disk ][ cannot
generate sufficiently strong write/erase fields.

This must all be in the FAQs.
