Hi!

I sure hope your livelihood doesn't depend on a disk...

I don't quite understand your description of the problem:  Is the damaged
disk one of those invloved in the copying?  I.e., did you mix up the
source and destination disks, being in a hurry?

If using "thin.prg" doesn't help, then it's not easy.  To use a disk editor
you'll need to learn some details of the way information is organized on a
disk.  (It is very much like MS-DOS disks, for which there is lots of
documentation.  The FAT, though, is 5 sectors long, and the root directory
7 sectors.)

It sounds like the root directory is damaged.  I suggest you make a backup-
copy of the damaged disk, then search the disk for sectors that look like
subdirectories.  When you find one, copy it to logical sector 11 (the start
of the root directory) and fill sector 12 with zeros.  You should be able
to read some files off the disk.  Files that were in the root directory
(rather than folders) will not be found this way, though...

Good luck!
