Don't really know.  You'd have to ask the F.B.I.  Reducing the entire drive
(including the chips) to dust would probably do about what I suggested would.
That is, it would likely make it impossible for anyone to recover data from the
drive.  As would placing it in a nuclear reactor, and probably doing a thousand
other things.  I just like my method, because once it congealed, you'd have
modern art.  LOL.
