actually it's a far more sophisticated ECC like code that even allows
single bit errors to be automatically corrected.

And disks do constant "signal strength" measurements and such and
relocate sectors before things go bad.

Remember that before using a sector on a new partition, you *always*
write to it (in a filesystem at least), and that's where the bad
situation will be detected *and remapped*.

If your disk is beyond remapping, the smart daemon (on by default) will
send you a nice mail saying that your disk is going bad.
