The last time I did anything like that was with a RSDOS program called
CoCoZap. It displayed a graphical picture of what it found on the disk and,
after studying the patterns one could discern the bad areas and make changes
that would allow the dist to at least be read. I do remember trying iton an
OS-9 disk, and for sure I did not try it on an Nitros-9 disk 8-).
