I have Ccleaner on 3 laptops, while running cleaner with wipe free space checked Gutman level 2 of the 3 complete the operation (granted with some time at the level) but the 3rd has never completed it gets to 100% and hangs and never completes the command by showing the files cleaned, even after 4 hours and it is a small HD only 20g, so it couldn't find enough info to wipe for 4 hours if it tried!:) XP Pro SP3 Any Ideas, Oh by the way have uninstalled and reinstalled ccleaner and have the latest version and it has done it on all versions on that computer only though.

Try running a check disk on the drive to make sure its ok.
