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...

Degauss, melt, mix it together with a high level of entropy, recycle it as scrap metal. Homemade foundry is doable on the cheap, a handy person* can turn hard drives into ingots and ingots into ash trays, planters, springs, model replicas of scifi items (set phasers to stun!).

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
https://www.nsa.gov/applications/search/index.cfm?q=demagnetization&x=23&y=12
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 FOIAs.
The Internet will never be degaussed, much less highly
magnetized and gaussed
IoT, Wayback, secure drops, searches, mail lists, the sun, sea
and sand.
