ntfswipe - overwrite unused space on an NTFS volume
ntfswipe [options] device
ntfswipe clears all or part of unused space on an NTFS volume by overwriting with zeroes or random bytes.
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 repeatedly 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 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.
