nwipe
nwipe secure disk eraser
nwipe is a fork of the dwipe command originally used by Darik's Boot and Nuke (DBAN). nwipe was created out of a need to run the DBAN dwipe command outside of DBAN, in order to allow its use with any host distribution, thus giving better hardware support. nwipe is a program that will securely erase the entire contents of disks. It can wipe a single drive or multiple disks simultaneously. It can operate as both a command line tool without a GUI or with a ncurses GUI.
