Extracting CDOS files - test-drb@ccmp.vtda.org

Masking out pin 8 (Index) on the 34-pin connector has no effect, I
still get:

Error reading diskette B: (Cyl 1, Side 1, Sect 1)
Sector not found

This sector DOES exist, both ImageDisk and TeleDisk can read it fine,
however no amount of "Retry" will convice 22disk to read it. 
Dave,

Have you considered using the Tim Mann software (cw2dmk) and the Catweasel?

That would pull up whatever information is on the disk and you could use it
to diagnose what is wrong with the disk.  It won't decode the CDOS file
format
but it will give you the sector headers and the raw sector data.

If you send me a disk, I will return it with a raw disk Catweasel image
...
 from cw2dmk.  Best of luck with your project.
