There were also many devious copy protection schemes used for games etc.
One common one was to punch a hole in a known sector (!) and if you didn't
get a read error when accessing it then it was an illegal copy; another
was to store data in an otherwise unreachable sector e.g. track 41 on a 40
track disk...
In short, good luck :-)
Hmmm... I just looked up the KryoFlux, and it's a fascinating device; it
actually gets right down to the flux level! I've never seen a 3" disk
before though.
