    Peter Gutmann has done outstanding research on recovering overwritten
    data from magnetic media. I think the gist of it: overwritten data _can_
    be recovered -- but the expense may be higher than the data is worth.

    And yes, practically all filesystems share this trait. WORM drives
    (Write Once, Read Many) do not. CD-Rs do not. Etc. :)
