Data Sanitization Methods

Data Sanitization Methods are the specific ways which the data destruction software utilize to wipe out or overwrites the data on a hard drive or other storage devices. There are different names for the data sanitization like data erasure methods, wipe algorithmsdata wipe methods, and data wipe standards. All are pointing to the same meaning. Usually, most of the data erasing programs will have multiple data sanitization methods which will help to make it compatible with any of the know drives.

Different Data Sanitization Methods

Without explaining too much, let’s dive into the list of data sanitization methods. We also noted the organizations where the methods originated from. Have a look.

  • Secure Erase
  • Write Zero
  • DoD 5220.22-M (US Department of Defense)
  • AFSSI-5020 (US Air Force)
  • NCSC-TG-025 (US National Security Agency)
  • ISM 6.2.92 (Australia)

  • CSEC ITSG-06 (Canada)
  • Gutmann (Peter Gutmann)
  • Schneier (Bruce Schneier)
  • Pfitzner (Roy Pfitzner)
  • Random Data
  • HMG IS5 (UK)
  • VSITR (Germany)
  • GOST R 50739-95 (Russia)

In addition, you will be also given the ability to develop your own data sanitization method on specific programs. So, be wise when choosing one.

Among these, the Secure Erase and Write Zero methods are known to be the most efficient and very easy to execute. Many experts suggesting this method where the entire sections of the hard disk will be replaced with a single character which will entirely wipe out each bit of information existed.

However, they may not be enough to fulfill each and every need of a user related to the data replacement rules. That’s why multiple sanitization methods came into existence which all has its own advantage on specific requirements. Some software also provides the Verify the Write feature which will verify each and every written section to make sure the write. It is a great advantage to confirm the action.
