Verifying backup CD/DVD results

[Bill Davidsen <davidsen@tmr.com>]

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.
