Not only can you carry out a scan to the normal level, Privary Eraser Free also enables you to zero fill your computer (which means overwriting the data so no tool can retrieve it – apparently), as well as clean to various US Department of Defense standards. Will leave data on the disk if the file size is greater than 32KB.There is also the option to change the level of file detection. First/last 16KB Erasure (File Erasure Only) – A fast, simple method for making files hard to find/recover.Pseudorandom Data (1 pass) – A fast sanitization method that writes random data over the existing data.British HMG IS5 (Baseline) (1 pass) – This is a single-pass method that serves as the baseline for HMG IS5.Russian GOST P50739-95 (2 passes) – This method was defined by Russia and uses 2 passes (the first writing zeroes over all data, the second writing random data) to sanitize a disk.Like US Air force 5020, the magnetic media section is just part of a larger document covering all sorts of information systems. US Army AR380-19 (3 passes) – A 3-pass system for sanitizing magnetic media defined by the US Army.Part of a larger document covering all sorts of information systems. US Air Force 5020 (3 passes) – A 3-pass system for sanitizing magnetic media defined by the US Air Force.British HMG IS5 (Enhanced) (3 passes) – This 3-pass approach is the more secure of two methods (Enhanced and Basic) defined in HMG IS5.US DoD 5220.22-M (8-306./E) (3 passes) – A 3-pass sanitization method specified by the United States Department of Defense.German VSITR (7 passes) – Developed for Germany’s Federal Office for Information Security, this 7-pass method is no longer used by that government for erasing classified information and documents but is more than sufficient for most civilian uses.Schneier 7 pass (7 passes) – Designed by Bruce Schneier, this method uses 7 passes and was originally laid out in Schneier’s book, “ Applied Cryptography: Protocols, Algorithms, and Source Code in C”.US DoD 5220.22-M (8-306./E, C & E) (7 passes) – A 7-pass sanitization method specified by the United States Department of Defense.Overwrites the data with 35 different patterns, some of which are irrelevant for modern disk drives. Gutmann (35 passes) – Designed in 1996 to erase drives when you don’t know the algorithm used to encode the data on the disk.
