Ahh, neat.  Two sectors of ECC can fix one that is completely destroyed?
 I was under the impression that you could only fix a few corrupted
bits, not an entire sector, but I suppose if you add enough ECC...  I
take it that someone has already made sure that the misbehaved software
only uses a single sector?
