linux - How do I wipe an entire hard drive using the Gutmann method?






Is it possible to securely wipe a hard drive with the method outlined here using dd and little else? I have an old PC and an Ubuntu server disc which I can run a shell from, but not much is included on that.


Answer



Not exactly an answer but in this day and age you are basically wasting your time trying to use the Gutmann method specifically.


Gutmann himself:



In the time since this paper was published, some people have treated
the 35-pass overwrite technique described in it more as a kind of
voodoo incantation to banish evil spirits than the result of a
technical analysis of drive encoding techniques. As a result, they
advocate applying the voodoo to PRML and EPRML drives even though it
will have no more effect than a simple scrubbing with random data.
