       ntfswipe [options] device

DESCRIPTION
       ntfswipe  clears all or part of unused space on an NTFS volume by over-
       writing with zeroes or random bytes.

OPTIONS
       Below is a summary of all the options that  ntfswipe  accepts.   Nearly
       all options have two equivalent names.  The short name is preceded by -
       and the long name is preceded by --.  Any single letter  options,  that
       don't  take  an  argument,  can be combined into a single command, e.g.
       -fv is equivalent to -f -v.  Long named options can be  abbreviated  to
       any unique prefix of their name.

       -a, --all
              Wipe  all  unused  space. This may take significant time. If the
              option --unused-fast (or -U) is also present, the faster  wiping
              method is used.

       -b, --bytes BYTE-LIST
              Define the allowed replacement bytes which are drawn randomly to
              overwrite the unused space. BYTE-LIST is a comma-separated  list
              of values in range 0-255 expressed in octal, decimal or hexadec-
              imal base.

       -c, --count NUM
              Define the number of times the unused space is to  be  overwrit-
              ten.

       -d, --directory
              Wipe  all  the  directory  indexes,  which  may contain names of
              deleted files.

       -f, --force
              This will override some sensible defaults, such as not  using  a
              mounted volume.  Use this option with caution.

       -h, --help
              Show a list of options with a brief description of each one.

       -i, --info
              Display details about unused space, without wiping anything.

       -l, --logfile
              Overwrite the logfile (update journal).

       -m, --mft
              Overwrite  the  unused  space in the MFT (main file table, which
              contains the file names, and the contents of short files).

       -n, --no-action
              Executes the wiping process without writing to device.

       -p, --pagefile
              ters.

       -u, --unused
              Overwrite the space which is currently not allocated to any file
              (but may have been used in the past).

       -U, --unused-fast
              Overwrite the space which is  currently  not  allocated  to  any
              file, trying not to overwrite the space not written to since the
              previous wiping.

       -v, --verbose
              Display more debug/warning/error messages. This  option  may  be
              used twice to display even more messages.

       -V, --version
              Show the version number, copyright and license of ntfswipe.
