I just recently reformatted my computer and I am using Windows XP. My hard drive capacity is 127 gigabytes. Well after I finished reformatting and installing programs once again, I noticed somthing wrong. I currently am only using about 20 gigs of my hard drive space so that would mean that it should say that I have about 100 gigs of free space out of 127gigs. However it is actually telling me that I only have 70 gigs of free space left. This is a NTSF system btw. I have no idea why it is saying that I am using 30gigs that I am not. I have tried doing chkdsk, disk cleaning, as well as a reading many forum posts, none of which help me. So please respond if you have any ideas on what I should do. Thanks!
