I ran ccleaner with wipe free space. Windows 7 Home Premium 64 bit. 5+ hours later, single pass, <500GB,, the time is still increasing. I canceled it, but my HDD shows hardly any free space left. Ran TreeSizeFree & there was a huge amount of data in system volume information. Had to delete all restore points to reclaim free space.
1. Why did the program continue to show an increasing time for wiping the free space, even after 5+ hours?
2. Why did cancelling the "wipe free space" operation not immediately reclaim space? Why did I have to delete all of my restor
