The scratch was not especially near the center of the disk. Also, I
was able to read the first 10 or so pictures before the fix, and all
of the disk afterwards. So a portion of the disk was in fact readable
before the fix.

Next time I backup, I don't mind doing an experiment on my old backup
disk. I'll make a light scratch, prove to myself that the drive cannot
read it, and then try to fix it with a marker. I'll post the results
if there's interest.
