| scrub | writes patterns on magnetic media to thwart data recovery | Mehr ... |
scrub iteratively writes patterns on files or disk devices to make retrieving
the data more difficult.
.
scrub can write patterns direct to disk, destroying any file system (preferred
method), or it can write patterns on files, or on file system free space.
.
scrub writes NNSA NAP-14.x, DoD 5220.22-M, BSI, 35-pass gutmann, or one of
several other selectable pattern sequences.
.
scrub operates at the POSIX system call level, thus it is portable to a wide
variety of hardware platforms. However, this means it cannot do certain things
like manipulate spare blocks on disks, etc.. |
