Correct. It is the same as Miles and Nautical Miles. The disk industry
choose 1000 as their yardstick because geometry of a hardisk has no real
relation to any particular numberbase (Except maybe numbers of heads) and
1000 is a much easier number to base calculations on for us mere mortals
:-)

away with this

Hard Drive Manufacturers work on MB and GB's being based on base 10 (eg
1000MB's in a GB), rather than base 8 (1024MB in a GB), so you always
end up with less than the indicated amount, as shown with David's
calculations.
Please feel free to correct me if Im wrong but this is certainly how it
used to be.

Tony.
