Let us start by emphasizing the benefits of DoD 5220.22-M and why it is most liked by the masses compared to the other methods. DoD 5220.22-M vs Gutmann Method: The ComparisonĪs we move forward, let us now compare the benefits of DoD 5220.22- M Standard and the Gutmann method. This function is overridden 35 times in total. The Gutmann method employs a random character, rather than the zero indexes employed by other systems, for the first four overwrites and the last four rewrites but uses a sophisticated overwriting pattern from the fifth to the thirty-first overwrite. Unlike a standard file erasure, using the Gutmann method on a hard drive forbids all data recovery methods based on software that considers information on the drive and most found troubleshooting tools. Peter Gutmann invented the Gutmann technique in 1996, and it is one of various software-based data sanitization methods implemented in numerous file shredder and data destruction applications, overwriting current information on the storage device or other external hard drive.
