Not quite sure being on the spot, but since the Apple specs say that
the whole space on a disk must be allocated in the partition map, it
can happen that the division between the main partitions (driver
partitions, payload partition, etc.) doesn't make the total of the
sectors on disk. The rest should be represented in the partition map
by a Apple_Free partition.
My 2 cents...
