Securely Wiping HDD

I heard from many security consultants that the best way to ‘destroy’ a HDD data other than drilling a hole into the centre of the HDD is to
1.  Encrypt the entire HDD with a random key string
2. Wiping it with DoD standard

I have written this python script which automates the process.

You can find the script at http://pastebin.com/fa324359

What I have done is to put this script in ubuntu and then use remastersys to create a bootable ISO.

This way, you can burn the ISO and pop the disc to any computers to wipe out the data.

    Is the bootable ISO you created available for download anywhere?

    I can upload the files to mediafire.com if you like. The iso file is about 800MB because I am using remastersys in Ubuntu.

    Alternatively, if you have an alternative site where I can upload the iso file, let me know. If not, I can provide the instructions on how to use remastersys in ubuntu to create this iso file.

    Let me know. Thanks. You can reach me at keith.lee2012[at]gmail.com

    Thank you for that Milo, I have now been thinking about it and I thought I could get a live CD that has Truecrypt and some wiping utility and do the same thing, it will be done in two stages but it is about the same result, I have found GRML live CD comes with Truecrypt and BCCrypt and I should be able to do it with it. There will be no need for you to upload the .ISO

    Thanks again for the offer.

    PS: Only the old version of GRML includes truecrypt this has now been discontinued but I can still use it.
