I found this link: http://swaj.net/unix/cdck/cdck-0.6.0.tar.gz which is
a program to read a CD or DVD and report on the goodness of the burn, in
terms of current and potential errors. I can't swear that the results
are accurate in terms of predicting future failures, but they are
consistent, in that a DVD identified as marginal, good, or excellent on
one machine will have the same rating on at least two other machines
using other brands of DVD reader hardware.
I have been checking my critical backups and reburning any rated less
than good. Only rarely do I see the excellent rating, which may reflect
my use of good but not premium media.
