Hard drive secure erasure

[roasted]

Guess what? I dont give a fuck, bitch.

I searched the entire document, and this was the closest I could find to destroying data:

5-705. Methods of Destruction. Classified material may be destroyed by burning, shredding, pulping, melting, mutilation, chemical decomposition, or pulverizing (for example, hammer mills, choppers, and hybridized disintegration equipment).

So, it's pretty much how I described.

Here's the fighter jet degausser.

Enough with the mudslinging, keep personal attacks out of here as we already have a forum for that shit!

Disagree all you like, but debate as adults!

I'll PM you address...

7200 rpm not 7200 terabytes lol that would be insaneee

[The Pat-Man]

lol yea should have worded that better.

That article makes me laugh. Its 6 years old, and completely ridiculous. Thats not a "fighter jet" degausser. The DoD doesnt eradicate disks based on application, they eradicate them based on data sensitivity. They handle anything classified top secret the same way (and its not that shitty degausser in the article, trust me), it doesnt matter if it was from a fighter jet, PC, or mainframe.

What makes more sense, this:


Or this:


I'll give you a hint, its probably the one that isnt sitting on a piece of wood and doesnt have a hand crank...

liquid nitrogen cooled superconducting electromagnet

It really sounds like you have first hand experience in this industry, lol. The process is exactly how you described. What powers the shredders, rainbows and unicorns?

Here is how they actually do it:
1. Direct attached, internal, disk overwrite (done with utilities built into the originating hardware)
2. Secure, detached, 7-pass (+ verification) overwrite (not DBAN, but an actual utility)
3. Degauss (the machine I showed, not some mythical liquid nitrogen bullshit)
4. On-site shredding (no belt sanders, thermite or other explosives)
5. Secure off-site e-recycling

Thats it. I would know because I have worked for multiple government agencies doing this exact process. What you described is exactly what I would expect from some aspie that has no clue how its actually done. You're not speaking from personal experience, you're quote a single article written by a fellow aspie.

Just keep telling yourself its done this way, and maybe one day it'll become true.

Ok, I'll keep the mudslinging and personal attacks out of here.

Encrypt, secure wipe, smash. Done and done, stop arguing.

Personally I'd go for secure wipe as being safest, then encryption, then obliterating then smashing with a hammer.

Someone doesn't know what "prototype" means...

How exactly do you expect a fighter jet pilot to securely overwrite, shred, and recycle a disk in the minute or two they have before ejecting? They can't, so they have to devise a new and faster method. Degaussing with a superconducting magnet fits the bill in this case.

How about a small camp about to be overrun by the enemy? No time there either. I suspect many leaders would give the order to use thermite grenades on the disks to prevent capture.

For someone in a secure homeland office, yes, you're probably right about current standard disposal procedure. But it wasn't always so. The furnace and belt sander methods I mentioned were back in the days of 5.25" drives. It makes sense they would update their methods with time.

This. All these kiddies thinking they are made from metal don't know shit. The reason they are glass is because glass doesn't expand much, is perfectly flat when made correctly, and it will take a metal film over in in which the information can be written.

Basically, open the hdd, smash the platters with a hammer, and then throw the whole lot into a fire. The temperature will distort the metal covering of the glass, destroying the information and the hdd. Depending on how hot the fire is, you might just melt the whole aluminium casing down into a blob...lets see them extract information from that.

Hell, if you are positive the fire wont be found until the hdd has been completely melted, just chuck it in there, no need for magnets and grinders and other shit. Any furnace capable of melting steel will destroy a hdd, as will any normal fire with a bellows/blower to increase the temperature.

Otherwise, the 2nd best way is to throw it into the river/ocean away from prying eyes, preferably somewhere with a very silty bottom so the hdd sinks and makes finding it hard/expensive.

If you want old data unrecoverable destroy the drive, properly. Melt it down.

Erasing and overwriting does not work. Use a USB as your operating system, have no hdd and use a burner and CD's to store information.

Microwave the CD's to destroy them.

[tuer502gt]

Have no RAM and use the USB as your ram.

[TheFlameofRevolution]

Or you can using wiping programs like DBAN or File Shredder

[stupid noob]

sup tzar nice thread too bad we got a bunch of fags bein fags in here. i thought it was interesting. didn't really learn anything from it lol but interesting none the less
