DBAN: Dariks Boot and Nuke

DBAN is a self-contained boot disk that automatically and completely deletes the contents of any hard disk that it can detect. It is a means of ensuring due diligence in computer recycling, a way of preventing identity theft if you want to sell a computer, and a solution to totally clean a Microsoft Windows installation of viruses and spyware. DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.
