Not quite. Things have changed in recent years. Now hard disks can
present a 'fake' geometry, making the drive seem smaller than it actually is.
(google for 'host protected area' for gory details).   Linux disables the
hpa during boot (otherwise, people start asking why they can't use all of their disks).

Unfortunatly, we don't identify when it's been 'clipped' that way for
reasons like 'hiding service tool partitions'.  There was some repeated
poking at it upstream, but I don't believe it's been solved.
