Crumbs. Not sure what's going on there then. I've just tested both of those discs back in the Victor (they're actually "new" copies made on just opened media). I can read and verify every sector perfectly on both discs, so it looks like it's the drive on the kryoflux (although I've just been dumping 360k IBM floppies and 400k 80 track FM floppies with it, and they've all been fine).

Ah, forgot you mentioned the drive earlier. Try dumping with adding either -dd0 or -dd1 to the dumping parameters. One or the other might improve the dump.

Also, do you have access to the original disks aswell?

Perhaps the copy is written just slightly misaligned.

OK, I've got some other original discs (that I know work as well) - alas, not that DOS or CP/M disk as original. I've a dos 1.25. Is there somewhere I can stick it that's convenient? Just given the drive heads a nice clean.

Pg 90+ of the tech reference manual goes into some detail on the format:

PM me and I'll put it at http://vintagecomputer.ca and replace the other disk image. I have been following this thread enthusiastically.
