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.
