sure, it's easy.

i found that the vast majority of burns are either all or nothing.  if
the burn failed, it's *very* rare the cd will mount.

is it 100% foolproof?  no.  nothing is.

however, i have extensive experience with my own and other peoples' cd
writers, and when i say "vast majority", i mean exactly that: "vast
majority".

in fact, i believe the only time i've seen anything to the contrary of
this, it was with cases of extreme overburning.

and if we're talking about 20 or even 50 burns, using something like
md5sum is just fscking obnoxious.
