I agree, this is a purely theoretical discussion for me.  I don't have such
sensitive data on my drives to want to nuke them.

Ah, yes.  The obligatory warning.  One method that I suggested would get the
gold star for dangerous, foolhardy, do not do:  Placing your hard drive in the
core of an active nuclear reactor.  Acid is not safe either - I started off in
chemistry...  I would sooner use 30 M hydrochloric acid than sulfuric acid -
why?  It is easier to obtain - the problem is disposing of what is left, as if
you pour it down the drain, it will start corroding your sink (unless it is
ceramic), and your pipes.  Not a pretty picture.
