tar is not as sexy as a live CD-R filesystem, but it obviously handles
these incremental issues better.

Assuming your dir structure has not changed much, it sounds like you
need to script (or find) a utility to check each file on the CD-R with
it on the drive.

Which is why tar is better than a live CD-R filesystem.

If you like, you can copy the files to a new dir on the drive, and then
use rsync to update it (rsync -rutl SRC DEST) and then reburn it as a
tar file.
