Is there
anybody in the San Francisco Bay Area that could create images of
three 5.25" floppies for me? I think that they are 720k with 256 byte
sectors, but I'm not sure. In any case, I've not been able to read them so
far.
1) Do you know what computer created them?
2) FM? MFM? GCR? (Sirius/Victor 9000?)
3) What have you triesd so far?
What messages do you get?
The difference between "General Failure" and "Sector Not Found" IS
significant.
I believe that they were created on an OS-9 68000 (the Microware, not
the Apple variety). I don't have the computer any more, just the
floppies. I tried to image them. If they are what I expect them to be,
then they would be 720k MFM. I've tried to read them with a 1.2M 5.25
drive, using fdutils, on a LINUX box, but I'm not sure that I've got
my drive strapped to spin at the correct RPM. In any case, fdutils
reports an error 40. I'm not sure that the hardware I'm using will
even talk to a 720k floppy.
