  There is no perfect mapping, since the sectors and gaps fall in
diferent places, and a spot which will not hold data may be in a gap
where you can "luck out" and never see it.

  I would run verify on the drive (from the controller BIOS) and then
take what you get. There's no really good way I've found to be sure you
have the right thing.

  This goes double if you are using the various skews which add so much
to performance on large file!
