    A lot of people believe that when they empty their deleted files from the Recycle bin then these files are permanently deleted from their hard drive. They're wrong! According to Microsoft (http://support.microsoft.com/default.aspx/kb/315672?):
    So how exactly do you permanently delete your files that you don't want other people to get their hands on? Microsoft offers a free command line utility called SDelete. You can use SDelete to securely delete all your files.


    To learn more about SDelete and how it works see this article:

    there's also a pretty cool free software called eraser

    it features different methods and u can also set the number of passes
    plus it integrates into windows explorer so u can right click a file and safe delete it.. or safe clean ur recycle bin

    its quite nice :)

    This makes me wish I still had the Floppy drive that a good friend of mine from the FBI gave me. It would erase a drive really good - It was used by the government to erase their drives :)

    look for either boot and nuke (linux bootable flash/cd/floppy image) or acronis disk director suite/true image both are really good at erasing disks beyond government requirements.

    well.. eraser can use US DoD 5220-22.M which "is sometimes cited as a standard for sanitization to counter data remanence." (so wikipedia says: D)

    That's actually not true. Bullets, magnets, drills, etc are not foolproof. There are people who specialize in recovering data from drives like that. From what I understand, software passes are actually the most effective (and several passes at that). That's all I can really say about it, but I have seen it happen.

    As an aside, I can recommend Blancco. You can get a trial, but it's a pay for utility with amazing capabilities

    You'd be surprised what they can recover data from. The only surefire way is to destroy the magnetic surface utterly. Turn it in to fine powder :)
