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