![]() ![]() A classic case of echo chamber knowledge distribution, the de facto adaption of this process was more of a marketing phenomenon than it was the result of any official policy supported by the Department of Defense.ĭoD 5220.22-M specifies a process that overwrites data on a hard drive with random patterns of ones and zeros. The DoD 5220.22-M standard for erasing or wiping data from a hard drive emerged early on in the evolving electronic data destruction business. Independent data erasure verification has moved to the forefront of certified compliance oversight."Approved by DoD" claims are misleading.Multiple overwrite passes can waste time and money.Regulations and certification programs now cite NIST SP 800-88 media erasure guidelines.Department of Defense no longer references DoD 5220.22- M as a method for secure HDD erasure
