In any case, teledisk is not that useful for
extracting information from
a non-PC disk (which is presumably what the police, etc, would want to
do). I can really see the point of being able to make a copy of a disk
for some machine they don't have. Some program like anadisk, which lets
you read sector-by-sector, make disk images, and so on, would be a lot
more useful to them I would have thought.
In my less ethical and more introspective moments I'd always wondered how I
could make a disk good and unreadable by anyone but myself. I played around
with unusual angular velocities and sub-normal GCR checksums on the 64 and
came up with a double key: both on the drive and the system. A device like
Teledisk, even if it could read GCR, probably wouldn't work for duplicating
such formats. The problem is that using something like angular velcotiy would
be keyed to a particular drive's characteristics and that would be the first
thing they'd confiscate.
