I have a 80gb harddrive and I was only using 30gbs of it. Then I started downloading stuff off of suprnova over night that tottaled out to be 2 gb of disk space and I let it download over night. When I woke up it said my harddrive was full. I only had 535mb of disk space left. How could this be. I ran check disk and it didnt find any errors, does anybody have any idea?
