I was just defragging my drive's free space when i noticed that the system volume information was heavilly fragmented. When the free space defrag was done i higlighted the approx. 150gb file and clicked defrag highlighted. The program crashed immediatley and it just deleted all the information. ALL my restore points and previous file versions are gone. Is this a bug or was it just the file was too big? Is there any way of recovering the file? P.S. I'm running win 7 32 bit if it helps
