I am impressed and intrigued that someone was still using an Apple II
recently enough for the disk content to be of forensic interest.
I did use an Apple II briefly in the early eighties. I seem to recall that
the disks were hardware sectored rather then the software sectoring we are
used to now. There was a ring of holes punched in the disk media near the
centre and a hole in the envelope, which allowed an optical sensor to
detect the holes. The holes were used to identify the sectors.
I am not sure if a modern 5 1/4 drive could read these disk but you could
try a Google search

These people claim to be able to convert most disk formats including apple

I would be interested to hear how you get on, if you can tell us.
Good luck

Subject: 5.25 Inch Disk Data Recovery
Hi all,
I would appreciate any help in trying to resolve a
problem I am having.
I am trying to recover data from some 5.25 inch disks.
They came off an older Apple system. (Apple 2?).
I have tried using dd, Ghost, Encase, FTK, Winhex and
Norton Utilites to view/image these diskettes without
any success.
It is not clear to me if there is still valid data on
these disks. My experience has shown me that data on
a 5.25 inch can get corrupted over time. Does anyone
know if the tools above could successfully read these
disks? I am using a 1.2 Mb drive. If these tools
can't do the job, does anyone know of a definitive way
to get at this data using an x86 or Sun system?
Thanks all,
Sety
