BCWipe

BCWipe securely erases data from magnetic and solid-state memory, by repeatedly overwriting special patterns in the files to be destroyed. In normal mode, 34 patterns are used (of which 8 are random); in quick mode, U.S. DoD (Department of Defence) 5200.28 standard are used with 7-pass wiping; and in custom mode, U.S. DoD 5200.28 standards are used with a user-defined number of passes.
