I keep hearing rumours that this is done with modern hard disks too, and that
if one side of a platter tests bad then that platter will still get used in a
drive with that surface mapped out (e.g. company releases a 2-platter 40GB
drive, and a 30GB drive which is identical but with one failed surface)
Never confirmed that one, but I can see how it might make financial sense.
