I seriously doubt you have 1 terrabyte of precious data. Another idea just hit me. What if you encrypt the data on the disk. Ubuntu has that thing now to create a Private encrypted partition. Do that, move your precious stuff in there. then unmount. That is supposed to be just about impossible to recover, even for the NSA kids. Anybody know if it is easier to crack an ecrypted file system than recover shredded data? pj -- Paul E.
