Securely erasing all data from a hard drive

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.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

@Nifle That question is about a Windows PC. There's not a trace of Windows left on this machine. I'm also asking specifically about the Gutmann method. – Blacklight Shining Sep 30 '12 at 17:02
Related from other Stack Exchanges (try a little bit of searching my friend): Ask Ubuntu: How can I securely erase a USB hard drive?, StackOverflow: How do I erase my disk? (In a secure way) (Ubuntu) and Security: How can I reliably erase all information on a hard drive?. – Ƭᴇcʜιᴇ007 Sep 30 '12 at 17:02
The answers in that question is valid for any OS (as the OS is irrelevant at that stage). – Nifle Sep 30 '12 at 17:05

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.

So I should just do one pass from /dev/urandom, and maybe one from /dev/zero and have done with it? – Blacklight Shining Sep 30 '12 at 17:06
/dev/zero is probably enough, but why not throw a random pass in there if you have time, as "Voodoo" can make you feel good sometimes, and that's important too. ;) – Ƭᴇcʜιᴇ007 Sep 30 '12 at 17:08

If you wish the delete all the data from drive and ensure it is all gone with no trace, if you are willing to simply burn another cd I suggest using DBAN as it will make the whole process a lot easier than using DD.

I don't have another CD… – Blacklight Shining Sep 30 '12 at 16:58
