wondering how you can tell whether a CD or DVD has corruption which
is being corrected or whether it is pristine. If I can tell, then maybe
when
there is corruption I could re-record the data before it becomes
unreadable.
Can't tell you the answer to that one, but it's an interesting question and
one I've considered for various equipment that has built-in error correction;
it's no good having that error correction if it silently masks errors
happening when the user could have otherwise done something about the faulty part.
Memory (at least in ECC form) and hard disks are two obvious candidates for
masking faults from the user...
