How much smaller? If it's only a few GB, then that's easily explained by the computer using base 2 math to calculate size and hard drive makers using base 10. The difference works out to about 24MB/GB. Then there's some overhead from the filesystem as well. So unless we're talking like 10% or more, it's normal.
Hey all new at this i have 2 hard drives and want to format them but they both say the are smaller than they really are, can anyone point me in the right direction.. I'm using xp pro if it helps one is a fire ball 40 gig and the other is a western dig 160 gig
