Pass 6: All addressable locations are overwritten with binary ones (the compliment of the above) Pass 5: All addressable locations are overwritten with binary zeroes Pass 4: All addressable locations are overwritten with binary zeroes Pass 2: All addressable locations are overwritten with binary ones (the compliment of the above) It runs DoD 5220.22-M twice and an extra pass (DoD 5220.22-M (C) Standard) in between. In 2001, DoD published the DoD 5220.22-M ECE method, a 7-pass version of the original standard. The final overwrite pass is then verified. Pass 3: All addressable locations are overwritten with a random bit pattern Pass 2: All addressable locations are overwritten with binary ones Pass 1: All addressable locations are overwritten with binary zeroes The following passes constitute the US DoD data wipe standard: The standard defines the implementation of three secure overwriting passes with verification at the end of the final pass. The DoD method is based on overwriting the addressable memory locations in hard disk drives with ‘zeroes’ and ‘ones’ as the binary patterns. The standard involves overwriting the previously stored data on a hard drive with specific binary patterns repeatedly through a specific number of passes. In the media sanitization circles, it is known as US DoD 5220.22-M data wipe standard. What is the DoD 5220.22-M Standard?ĭoD 5220.22-M Standard is a widely recognized method for data erasure used by government agencies and organizations worldwide for performing drive erasure. Finally, it gives you an overview of how to implement the standard for erasing hard drives at an industrial scale using DoD data wiping software. It also deep dives into the steps involved in the US DoD data wipe standard for wiping hard drives. Department of Defense (DoD) 5220.22-M standard for drive erasure. This article provides an insight into the U.S. Other examples include New Zealand Government’s Community security bureau (NZSIT), British HMG (Her majesty’s government) Infosec standard, etc. Air Force have their data erasure standards.
For data erasure, these standards determine the overwriting patterns and passes set by government agencies and private institutions across the world. There are numerous standards defined over the past several decades to govern data wiping and other data destruction techniques for safe and compliant media sanitization practices.
