Seriously, if you look into the standards and see just
how much of a
laser-buned disk is used up for error control, it makes the HDD space
used for formatting look downright frugal.
I don't expect to ever see that kind of read error on a DVD (i.e. the
data reads back with no reported errors but is incorrect). The odds of
that
are astronomically low (and I'd never notice 'cos no error was reported
:-)).
What I worry about is part (or all) of a DVD or CD not reading at all.
All
the error correction stuff built into the media just hides how close I
really am to that much more interesting point in the life of that
particular piece of media! (There are tools out there which can read the
raw bits/pits, reconstruct the intermediate layers and tell you how
scratched your media looks today. I've not found one that tells you,
in some convenient way, how long it is likely to be before the media
has degraded seriously).
