    When you delete something, it is not actually deleted but moved to a special folder (recycle bin). If you empty the recycle bin, the file is removed. The info keeping track on where it is stored that is. The actual 1:s and 0:s on the HD still remains, but are allowed to be overwritten if a new file is created. Using certain programs, this data can be reclaimed and the files recreated. Of course, if you overwrite it, with that program (Eraser) for example, it is gone forever...

    There was a thread on the GF board on this exact same topic a bit ago. Search for it.

    Maybe all data will be gone, be sure if you do a quick format '/q' not all data will be gone...

    To delete ALL data, run fdisk, delete de partitions, create a new one, and than format it.

    Ive a program that will even retrive after a fdisk its caled R-studio
    its realy good but takes ages.
    The only real way to get rid of all your data is to do a low level format, some bios let you do it.
    Its what they do at the factory before any format is done on the disk
