For any BIOS using the CHS (normal, or large) translation mode,
the maximum cylinder value is 16,383. The CHS mode limits the BIOS
to being able to address a maximum drive size of 8.4 larger than
8.4 GB the BIOS must support the Logical Block Address (LBA) mode.
LBA uses the MAXLBA value as the addressing method to access the
cylinders on drives larger than 8.4 GB. Both the mother board and
the Operating System (OS) must support extended interrupt 13 (Xint
13) in order to prepare, format and access information on any drive
larger than 8.4 GB.
 

This occurs are every drive I use to some extent. When you figure out what the drive should show up as in fdisk based on the MaxLBA versus what it actually reads as, there is a difference of anywhere from 0.1 to 7.8 MB. If the MaxLBA is an integral multiple of 255x63=16065 then no space will be lost. Otherwise, you'll lose a small amount. Remember that on a 120 GB drive 7.8MB represents less than 0.007%.
