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?).
If they came off an Apple 2.. you will probably need to get an Apple 2
box set up to read them. The reasons being is that the RPM speed, write
size, and other items are particular to that hardware. [A lot of these
were able to be set by the disk itself which is how I remember a lot of
the copy protections worked.] I am pretty sure that you couldnt even
read it on a very old Apple Mac with a 5.25 drive attached without
special hardware.
You would most likely get garbage trying to put them into any PC
hardware because of that (what the apple sees as a 1 might look like a
series of 1's and 0's to a PC ro Mac hardware.)
I had to get a bunch of data from an Apple 2 a while back and thankfully
found someone who had one in a garage. I was able to get the data off of
18 year old floppies and out of 100 only 4 were bad.
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
