I had a simular issue with one of my hard drives. I do some DVD burning from time to time, but I only have one drive. The information is taken from the DVD and stored into a temp folder on a 80GB drive I have. I noticed that one day, it said I have 36GB of informaiton on it. Turned out to be all those temp files from the DVDs I was burning.
1. Is this partition on the same hard drive?
2. Or is it a separate drive?
