Drives have remapping capability, but it's the first I've heard of HD
firmware doing it automatically. I'd be very interested in reading
the relevant documentation, if you could provide a pointer. Seems to
me if a drive *could* do this, you'd certainly want to turn it
(automatic remapping) off. There's way too much chance that a system
will read the remapped sector and assume that it contains the
original data. That would be hopelessly corrupting.
