[ale] [OT] Mojave Experiment

[Greg Freemyer]

Jeff,

This is the only quote I've seen about the NSA's tests.

"Interestingly in the fall of 2004, the U.S. National Security Agency
(NSA Advisory LAA-006-2004) found that a single overwrite using the
above process is sufficient to render electronic files unrecoverable."

I've tried to get the Advisory with no luck.  You can google for the
above and find the original quote.  The latest NIST document clarifies
by saying over 15GB cannot be recovered by laboratory means after a
single pass wipe.

The NIST doc only applies to confidential data I believe, not Top Secret etc.
