I'm on Windows Vista, my hard drive is 150gb.
I have been using defraggler for years with no issues. Recently I realized I hadn't defragged in a LONG time. I mean like months. So I figured I'd let it do it's thing. I started it defragging and left it overnight. When I woke up the next morning it was still going, ok no big.
When it finally finished it said it had cleaned up about 30 gigs of crap. Woohoo, yay me. But within a couple of days this was full again. I hadn't downloaded anything. I hadn't deleted files, moved them. I really hadn't done anything other than piddle about on the internet. I didn't understand why this happened but no big. Tonight I decided to let it defrag again thinking it would clear the problem up. I started out with 15 gb of free space (so it said) , 12% free. It is now defragmented 49% and I have 6.1gb free, 4%.
It has not finished the defrag, but usually the amount of free space I have goes up not down. So I'm a little freaked out. Also I tried googling the problem and keep reading about shadow copies? But I'm an uber noob when it comes to this sort of stuff. Does anyone have any idea what is going on? How to fix it? What the heck are shadow copies and is it possible that is my problem?
PS. I'm pooped, and tired of worrying over this thing. I'm off to bed and I'll check it again in the morning. If this is normal feel free to have a good laugh at my expense and say so.
Night y'all <3
