NAME

6       nwipe - securely erase disks
7

SYNOPSIS

9       nwipe [options] [device1] [device2] ...
10

DESCRIPTION

12       nwipe  is  a  command that will securely erase disks using a variety of
13       recognised methods.  It is a fork of the dwipe command used by  Darik's
14       Boot  and  Nuke  (dban).   nwipe is included with partedmagic if want a
15       quick and easy bootable CD version.  nwipe was created out of a need to
16       run  the  DBAN dwipe command outside of DBAN, in order to allow its use
17       with any host distribution, thus giving better hardware support.  It is
18       essentially the same as dwipe, with a few changes:
19
20       - pthreads is used instead of fork
21
22       - The parted library is used to detect drives
23
24       - The code is designed to be compiled with gcc
25
26       - SIGUSR1 can be used to log the stats of the current wipe
