The way Windows estimates Hard drive space is a little unusual and hard to understand. What it tells you is left is actually more of a estimation rather than the actual. Fragmentation and running on the fly makes it look smaller in size. just formating the drive it will tell you there is 20 megs less than factory. It is difficult to explain in full but it shouldn't be that big of a problem once you start using it. Windows also automatically divides a slice from the hard drive to use as virtual RAM. along with paging files. basically windows is a hog for the hard drive as much as the ram. You could disable the auto backup feature if you feel you wont need it, but only if your very careful.
