I am making an assumption you are not willing to go get Partition Magic to reclaim the space and that you know how to convert from binary bytes to decimal bytes. If this is acceptable go read http://partedmagic.com/wiki/PartedMagic.php
And thats total. It used to have a second partition that was like 12 gigs but I deleted that when I used my restore disk so i dont know how i lost this much. Any help would be wounderfull.
