This is not nearly as big a problem as it used to be.  Drive
manufacturers need to adhere to an IDEMA standard which requires them to
use a specific LBA count for each capacity class.

I.e. a 500GB Seagate drive must have exactly the same number of sectors
as a 500GB Western Digital or Hitachi.

The IDEMA LBA standard applies to 3.5" form factor drives over 160GB as
well as 2.5" FF drives over 80 GB.
