I just found this thread via your webpage.
I have a private version of diskripper that will do a disk density scan, and will help find modified tracks.
I also have quite a few original C= disks ~4-500, so perhaps some might be of help if you are still working on this.
The more copies there are of these disks, the greater success in generating a good copy out of them, at least 3 needed.
