Darik's Boot and Nuke (DBAN) is a free erasure software designed for consumer or home use. However, users should be aware of its limitations, especially for larger environments such as a company or organizational network. Limitations include:
- We don't guarantee secure data erasure
- Limited hardware support (eg. no RAID dismantling)
- No customer support
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.
