These three methods apply to sanitizing an entire physical disk, but not specific files or folders. There are currently three conventional methods for sanitizing SSD’s. In this article, the term 'disk sanitization' refers to the process of eliminating all data on the storage device so that it is impossible to recover. If present, the cathode ray tube must be destroyed.Article Summary:This article explains the industry standard methods of disk sanitization for solid state hard drives (SSD).ĭisk Sanitization Methods for Solid State Hard Drives Inspect and/or test screen surface for evidence of burned-in information. Run five pages of unclassified text (font test acceptable). Destruction required only if classified information is contained. Destroy - Disintegrate, incinerate, pulverize, shred, or melt. Perform k above, but increase time by a factor of three. Perform an ultraviolet erase according to manufacturer's recommendation. Perform i above, then c above, a total of three times. Perform a full chip erase as per manufacturer's data sheets. Overwrite all locations with a random pattern, all locations with binary zeros, all locations with binary ones. Remove all power to include battery power. Each overwrite must reside in memory for a period longer than the classified data resided. Overwrite all addressable locations with a character, its complement, then a random character.į.

THIS METHOD IS NOT APPROVED FOR SANITIZING MEDIA THAT CONTAINS TOP SECRET INFORMATION.Į. Overwrite all addressable locations with a character, its complement, then a random character and verify. Overwrite all addressable locations with a single character.ĭ. US Department of Defense 5220.22-M Clearing and Sanitization Matrix MediaĬ.

triple data overwriting for the destruction of remains of sensitive data. To conform this security standard in KillDisk Professional version this approach has been implemented, i.e.

US Department of Defense in the clearing and sanitizing standard DoD 5220.22-M recommends the approach 'Overwrite all addressable locations with a character, its complement, then a random character and verify' (see table with comments) for clearing and sanitizing information on a writable media.
