This has to do with the way that hard disk manufacturers count disk
space. A kilobyte is 1024 bytes, a megabyte is 1024 kilobytes and a
gigabyte is 1024 megabytes. These are the definitions that the computer
uses (1024 is 2^10, as computers use base 2, binary, instead of base 10,
denary).

However, hard disk manufacturers count in 1000s rather than 1024s. This
means that 1GB for a disk manufacturer (1000^3 bytes) is actually
0.931GB ([1000/1024]^3) for everyone else.

Thanks,

Phil
