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.:
-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.:
