An algorithm is a type of useful method in which a specific lists of instructions are defined for completing a specified task. Disk Wiping algorithms are used by Drive Wipe software to completely wipe the hard disk. The effectiveness of the software is defined by the algorithms that the software is using.
Stellar Disk Wipe software uses the following powerful and effective algorithms to ensure the complete erasing of the hard drive:
Zeros (1 pass)
Pseudo Random ( 1 pass)
Pseudo Random & Zeros ( 2 passes)
DoD 5220.22 - M ( 3 passes)
DoD 5200.28 Std ( 7 passes)
Russian Standard - GOST ( 7 passes)
B. Schneier's Algorithm ( 7 passes)
German Standard, VSITR ( 7 passes)
Peter Gutmann ( 35 passes)
US Army AR 380-19
NATO Standard ( 5 passes)
US Air Force AFSSI 5020
Here the word passes means the particular algorithm overwrites the data for the given number of times.
