Melt it down and mix it enough, and there's no recovery because nothing is

operating on a budget.
But entropy *can* always be reversed, if the person trying is willing to
put more energy into it than the person destroying it (and they have an
idea of what they're trying to put back together... individually encrypted
files on an encrypted hard drive that was over written nine times, melted
along with other materials and then turned into cheap trash can has enough
obfuscation that it should be "practically" impossible without a
supercomputer.)

Hi Michael,
But you do get the point...don't you...Michael... :-) . Even the NSA
physically destroys the storage media...It even recommends degaussing and
other tools for destroying any residual information on the storage systems
which they wish to dispose of, but they still destroy the media. GCHQ also
physically destroys the media. Now...why do you think that is? Could it
be because, even with the best forensic and erasure tools in the world,
they are uncertain of the outcome, uncertain enough about the ability to
recover data, so that they have to dispose of their storage equipment by
having to physically destroy it.
Why not recycle it, send it to the likes of India or China or some of
the other developed and developing countries, if they are sure that erasure
works? Sell it off, save the taxpayer money...that is a lot of storage
wot gets written off every year...3 years write down on computer
equipment. Of course, it is probably just good security practice and keeps
the security bods happy... :-) . Now, where does that leave the Apple
erasure process in USG v Apple, one wonders....just a conjecture by the
way...a mere spes...

Tx for the url, John. I had a look...NSA recommends that all storage
media as well as being degaussed, otherwise sanitised, should be physically
destroyed on disposal. SSE as well as other storage media should be burned
to ash.
No recycling of NSA hardware storage systems then, all have to be
physically destroyed...must be a reason.
As an aside: The NSA degaussing procedure reminded me of my younger
days as a tv repairman, in the days when colour televisions were made out
of glass and metal and wieghed a ton. We used to carry around a degaussing
coil, so that we could demagnetise colour televisions. In the good old
days, colour televisions had a large metal plate, full of precisely
engineered tiny holes, behind the glass flourescent screen of the colour
tube. (not like todays bit of plastic monitors) The metal screen tended to
get magnetised over a period of time in two ways, one because it was just
sitting there in the same place in the house all the time and the Earth's
magnetic field used to magnetise it. The other way, was when the
housewife...or perhaps house husband (a very rare person indeed in those
days) used the vacuum cleaner and switched it off too close to the
television set, so causing the magnetic emanations to corrupt the metal
screen. Although every screen had its own degaussing coil surrounding it
which switched on for a short while, whilst the television was warming up,
it sometimes wasn't strong enough to degauss the metal. The symptoms of
this magnetisation were a change of colour on the flourescent screen and a
series of rainbow like patterns, due to the photons being deflected in a
slightly different direction as they went through the scan coils on to the
holes in the metal screen, so hitting the wrong flourescent dots on the
glass screen at the front. Customers used to phone us up in despair, pink
faces being turned into multicoloured skins. They were most impressed
when us guys came along and did our little bit o' magic, switching on our
degaussing coil and waving it around the screen like a magic wand and
saying "Abracadabra". Got many a tip out of that...:-) .

NSA has several guides on degaussing and demagnetization of media

However, not likely to disclose the very best and latest about
anything, but
will provide, like GCHQ and others, guidance on "information assurance"
through university partners, contractors, conferences, hearings, study
commissions, web sites, blogs, dual-hatted comsec experts, ex-officials
now in business, unauthorized disclosures such as Snowden's and
Manning's,
and the industry of dumbfounding, tail-chasing, redacted, cherry-picked

The Internet will never be degaussed, much less highly magnetized and
gaussed
IoT, Wayback, secure drops, searches, mail lists, the sun, sea and sand.
