Data corruption

Shouldn't it be possible to write a program that takes the record length
and tries to get a record at every [offset] bytes, and reject the bad ones
based on some (as yet undefined) criterion?  Then just rebuild the indexes?

Define "corrupted".  Actually, are the bytes corrupted, or is the record
offset altered because data went missing.  I would -think- just altered,
but you can never really rule anything out without verification.
