scrub-1.7 Release Notes 2006-02-14
========================================================================
NOTE: This version is a significant rewrite since version 1.6.
Major changes in addition to general cleanup and better documentation:
* The new default scrub patterns satisfy NNSA Policy Letter NAP-14.x,
and are appropriate for modern PRML/EPRML drive encodings.
The old scrub patterns as well as a set of patterns that minimally
satisfy DoD 5220.22-M (still appropriate for older MFM/RLL drives)
are selectable on the command line (-p).
* The algorithm for generating random bytes has been made more efficient
and more random using an AES counter mode algorithm.
* Device capacity is determined using OS-specific ioctls. The size is
overrideable on the command line (-s).
* [Mac OS X only] A file's resource fork is scrubbed if it exists.
