If you are selling, donating your PC you need DriveScrubber. Simply deleting files, pictures, or documents - even reformatting the hard drive - is not enough. Anyone with basic computer knowledge can recover and steal the private information you thought was gone. U.S. Department of Defense standards for secure data deletion require seven overwrites of the target drive space; DriveScrubber lets you overwrite up to one hundred times, so even the most sophisticated recovery and forensic methods cannot recover your data. DriveScrubber also lets you wipe only free drive space, keeping the operating system intact. Use it to keep personal information out of the wrong hands, or even to clean up after a stubborn virus or spyware attack.
