    Why does Mac OS X shows a 250GB drive as 249.42, while Windows 7 shows it as 232GB?

    Because OS X uses decimal system whereas windows uses binary system to calculate the capacity.

    They are not actually getting bigger. It is just how OS calculates the values. Just because it shows more GBs does not mean it actually has more bits.
