There is always overhead in formatting/partitioning a hard drive.  This includes
the data stored on the disk to locate the partitions, etc.  In addition, the
Apple fAdv.Disk.Util locks out bad blocks, and "saves" some of the disk space
for possible future replacement of subsequently occurring bad blocks.  Still,
5 meg seems like a lot.  Of course, unit-to-unit variations in the actual
amount of usable disk space occurs with all HD brands.  I formatted an Apple
HDSC20 hard drive with Apple's utilities and got exactly 20 meg.  Later I did
a low-level re-format using SCSI Hacker, and wound up with 22 meg.  The
shareware partitioners don't "reserve" space.
