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. 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.

EXAMPLES

ntfswipe -a /dev/sda1

ntfswipe -dms /dev/sda1
