Don't use the partition, such as /dev/sda1, but the whole drive, /dev/sda which should also get the partition tables. Formatting a hard drive just installs a new inode framework and root directory. The data itself is still there for something as simple as: dd if=/dev/sdX which will spit it all out to the screen with only the holes created by the installation of a new filesystem framework being invalid. But /dev/urandom written to everything 3 or more times should render the data unrecoverable unless they wanna call out the guys with the electron microscopes to read the edges of the track byte by byte. >Thanks > >Bob Cochran -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
