It is possible that the data on the disks may be corrupt, but it is also
possible that the disks are perfectly fine and that the old Mac 5.25"
drives work in the same way as the Mac 3.5" drives (ie they use variable
spindle speeds depending on the physical part of the disk being written
to). In order to find out you're going to need to get hold of an old
Mac system with a 5.25" floppy drive in it (a floppy drive in a PC won't
work as they don't support variable spindle speeds) and then try to read
the disks.
It's also possible that you might be able to read the disks using
Anadisk (from Sydex), but I've never tried that route.
Best of 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
