NAME

       ntfswipe - overwrite unused space on an NTFS volume

SYNOPSIS

       ntfswipe [options] device

DESCRIPTION

       ntfswipe clears all or part of unused space on an NTFS volume by overwriting 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 hexadecimal base.

       -c, --count NUM
	      Define  the number of times the unused space is to be overwritten. If both options --bytes and --count are set, the space is repeat-
	      edly overwritten this number of times by each of the values in the list.

       -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
	      Overwrite the Windows swap space.

       -q, --quiet
	      Suppress some debug/warning/error messages.

       -s, --undel
	      Overwrite the space which had been allocated to a file which has been deleted recently and is still undeletable. This option is  not
	      compatible with --bytes and the replacement bytes are random ones or taken from a standard list.

       -t, --tails
	      Overwrite the space at the end of files which is unused, but allocated because the allocations are always done by full clusters.

       -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 previ-
	      ous 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.

EXAMPLES

	      ntfswipe -a /dev/sda1

	      ntfswipe -dms /dev/sda1
