About DoD wiping method
DoD 5220.22-M (DoD standard) is a data sanitization method first published in US Department of Defense document #5220.22-M. It specifies a process of overwriting hard disk drives (HDDs) with patterns of ones and zeros. Learn more about DoD disk wipe from the following FAQs:
▶ How many passes is a DoD wipe?
DoD standard is a 3-pass wiping method. It overwrites all addressable locations on your hard drive with binary zeroes, binary ones, and a random bit pattern from the first pass to the third pass.
DoD 5220.22-M ECE, the extended version of DoD 5220.22-M, is a 7-pass method.
▶ How long does a DoD wipe take?
It depends on your hard drive capacity greatly. Sometimes the interface type also has effect on wiping speed.
▶ Can data be recovered after a DoD wipe?
A DoD wipe will prevent all software-based file recovery methods as well as most (if not all) hardware-based recovery methods from lifting information from the drive.
