    Secure Formatting Tools

    Can anyone reccomend tools to securely format hard drives so data can not be recovered?

    I used one a few years ago, but I forgot the name of it.

    Thanks.

    Just what you reformat. Reformats are completely recoverable, however "secure" deleting it, or writing zeros to it, are not. They cannot be recovered. But some software, will recover your hard drive up to 15 reformats before.

    That's just it they are still there until you write over them.

    No it doesn't slow down your drive at all. As far as windows is concerned data doesn't exist there with a normal format but it's still magnetically on the disk until something replaces it.

    I'd imagine if sensitive data exists on the hard drive, it should be formatted completely. Also if you were to sell the hard disk.
    <?php include_once('signature'); ?>

    Another example would be of thinking of a audio tape that has recorded material on it. Reformatting would be somewhat like rewinding to the front, and recording over what you previously had.. but the part's you havnt gotten to are still there.
