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