Just fire a few rounds into it, or open the case and scratch it with anything. You could also put the disks in the microwave... a bit less dramatic
than explosives but it will get the job done. The old way that the ORNL complex disposed of old drives was just to shoot them several times with a
rifle

Are you speaking about workable or not workable hdd? If you use full HDD enscryption, after that format it and 5 or 6 times write noise on it you
doesnt need to worry about safety i think. But its better to use HDD not at all, use Tiles on sd card for dangerous info.

What does the hard disk drive physically consist of? Inside the metal shell?
Spindles, reader heads et cetera are not awfully important. Assume that whoever is working at the remains of the hard disk drive is using professional
hardware to seek for fragments of information on the non-obliterated sections of the disc. Then what?
What is the magnetic material carrying the information? Cobalt what?
And what does the disk consist of that rotates under the read-write head?

I'm surprised nobody has mentioned Thermite, cheap and fast and also effective.
Just keep a spare 500 gram bag hanging around for when the cops come knocking.

You need an optimum amount. Too little and it does not destroy the whole drive - too much, and it takes too much space inside the computer. Oh, and
too conspicuous fire inside the computer, too.
Also: does your optimal thermite composition depend on whether your disc platter is aluminum (melts at 660 degrees, oxidizable) or glass/ceramic?
Does a hard disc stay readable all the way to Curie temperature, and what is it?

Yours, I find it hard to understand what you're saying sometimes.
For example:
| Quote: |
Yes you read correctly. Acides, explosive or thermites. I' m seeking the best way. The best is that wich leaves no traces.
I' ll try to realize to best way.
|
Acides is a simple typo, the sentence became kind of broken when you said explosive, it should be plural and it should be 'and thermites' you also
need to add in what that answer was in reference to, as I didn't really understand what you meant by that.
Seeking the best way to what?
I'm not trying to insult, I just feel that people could understand you better if you write in complete english.

How was that not you? Did you not type that reply?
I can't read your replies as they don't make sense, it doesn't matter if you were quoting someone or not.
@chornedsnorkack
Haha I didn't intend on fitting the thermite inside the computer chasis, it would be much more practical to leave it open and simply lift the
harddrive out, go outside, place bag of thermite on top of hard drive and light.
I want the drive wiped, I don't want my house burned down in the process lol

Zts was quoting a post from somebody else and was simply showing you what had been stated earlier in this thread.
All of Zts' comments make perfect sense to me, and I have never had an issue understanding what he is attempting to explain.
You should go to the first page of this thread and read the posts, you will see that Zts was not the individual that posted the comment that you had
an issue with understanding.

Whoops, I assumed zts16 was the same poster as the first reply, aldofad.
Apologies zts, your comments make perfect sense to me aswell.
Can we get back on topic anyway?

As Cheddite Cheese said earlier, use an overwrite program, like Darik's Boot and Nuke:
http://www.dban.org/
But thermite is always a good idea; as would thermate or a melting furnace, like MrHomeScientist made. Disassembing and smashing the platters to bits
also works.
At the end of the day, simulating atoms doesn't beat working with the real things...

I believe it can still be recovered although it is incredibly difficult, data needs to be overwritten for data to be truly removed and bad sectors
will always have data written on them.

Well, that depends on whether you count on having the time to remove the harddrive and carry it out... rather than fitting the demolition charge
inside the computer chassis and set it off inconspicuously when the computer is searched.
How much temperature is needed to reliably destroy magnetic memory?
The underlying platter is either aluminum, glass or ceramic.
Aluminum platter melts at 660 Celsius. And melting it into liquid would destroy the magnetic record on surface.
Glass and ceramic may be more resistant. They might be cracked and shattered by thermal stresses, or soften and bend, but this does not mean specially
suited reader heads at low speeds cannot read magnetic records on the fragments.
Heating the magnet over its Curie temperature would destroy the magnetic record, but the Curie temperature of cobalt is as much as over 1100 Celsius.
But the magnetic covering of hard disc is supposed to be included in a multilayer coating. What do these layers consist of?

I think you're going to add to your list of felonies when the cops are lifting and seizing your equipment and a bomb goes off inside the chassis
taking hands off the cops.

It would be easy to destroy a hard drive if hard drives were make out of nitrocellulose. Simply light one end, and FWOOOSH...gone. If this sounds
absurd, well, that's because it is. What I'm saying, though, is if you want to destroy an object quickly, it makes sense to not make that object
something that is difficult to destroy.
Big 5.25" hard drives have considerable mass, and trying to destroy one in your living room will either, A). Burn your house down with thermite. This
is not really hypothetical. It WILL happen. Or, B). Destroy the hearing of both you and your little cat when your hard drive detonates unexpectedly
(like while you're sitting there using the computer one day). You'll be sitting there surfing the web, and the cat will be sitting there licking
herself, and then suddenly "BANG"!!! No fun.

That sounds like such a weird and specific story that it would have had to come out of personal
experience...

HA HA! No, I'm just waxing pathetic (poetic). That, and I've had way too much caffeine. Anyway, it's far better to keep your ambitions small.
Try destroying SMALL things, like external uSD or USB cards. That way the whole mess can be contained in a small high-temp enclosure.
It often takes more to destroy something than you'd think. I was not surprised to see that the circuit boards were recovered almost intact from the
incident in Boston. I've seen a 1lb shape charge go off right next to a circuit board, only to find the board 100 feet away, almost reusable. If
portions of a hard drive platter are still recoverable, I can see the magnetic patterns when mounting it up in an SEM. Certainly a dedicated lab
could read data off of that.

Yeah, I would advise against blowing up a hard drive. I don't know how good data recovery techniques are, but chances are some data can be recovered
from undamaged fragments of the platters. Keep the temps high (you want to hit the Curie point and remove the magnetism of the platters), and you want
to ensure the platters end up in very small pieces or melted. Thermite or melting the HDD itself does this. (I would recommend thermite though.)

In a situation where you don't have much time, and if you really wanted to go far, you could build a hidden enclosed high-temp furnace to throw the
hard drive into. If that's not enough you could possibly make a device that lets you connect an electrode to each end, then puts a high-voltage
current through it prior to putting it in the furnace.
