There are reports data has been recovered from fragments of hard disk platters. Thanks to redundancy of writes, sometimes entire files are recovered from small fragments.

Presumably recovery can be done from flash chips, memory chips, anything used for storage, and in some cases used for transmission (from packetization and temp storage along the route). Recovery can be done from a distance without physical contact,either
simultaneously with movement or at rest.

CIA-NSA Special Collection Service's purpose is to do just that: what cannot be grabbed from the spectrum is burgled with breaking and entering or by implants (active, passive, inert).

The inert is the hardest to discover for it emits no signal, merely silently reflects it. And some of those are fake or easy to find to conceal the doozies.

Some of us emit signals from hearing aids, pacemakers, fitbits, teeth braces, prostheses,
along with the usual irrespressable unable to STFU EENT and the gadgets before us ratting on us.

Now then, why physically destroy storage media? To pass the time, feel good, please deity, erase the thought that it is to divert attention from thieves already here and gone. The Guardian sent a Fedex package to the New York Times supposedly containing the Snowden files, what was in it was a package of one-time pads with GCHQ at top and a note stating "your little fun is just beginning."

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!).Â

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...:-) .
