    Maybe it would, but it's an unpleasent and slow procedure. You're most
    probably not supposed to block the machine for a week.

    This depends on the file system. E.g. reiserfs will store data in "file tail"
    areas, which aren't available for dd, except for the (single) file tail.

    IMO: If the admin was trustworthy enough to store the files on that system,
    you can also trust him not to undelete the files.
