Making Computer Data unrecoverable in 1 Second

Code:

There comes a time in every hackers life where they get paranoid. In a world where some poor guy can be arrested and serve 10+ years
because the lawyers, juries, judges and general public dont understand the technolgy or the conditions of the laws applying to that

and my computers are confiscated just the topics Im interested in (computer security, hacking, etc) are probably going to be used t
technology. Take someone like me, who has countless ammounts of information on their PC. If for whatever reason something stupid ha
po fuel a media campaign to smear my name and turn public opinion against me, regardless of my innocence... and it aint hard either:  "Hacker arrested in NY, Feds charge he could start WWIII, and planned to do so" 
to the general public (ie. non-hackers)
 
ell then, what if you dont want that to happen?

some expert says my files were heavily related to "encryption, hacking and phone hacking" and that I visited "underground websites" etc. See what Im saying? The label hacker these days seems to equal "evil intent"
m a hard drive doesnt mean that it isnt recoverable. Formatting the drive doesnt mean the data isnt recoverable. Hell, even throwing the drive in a campfire doesnt assure the data cant be recovered as the efforts of Jeremy Kaplan (PC Magazine executive editor) and Ontrack Data Recovery showed.

Hmmm. so how do you make data non-recoverable? Can it be done? Well, yeah. For example, Peter Gutmann came up with a method of making data recovery more difficult by writting over the disk several times with random useless bits of info.  Hey, great.. but you know what? When a federal agent is ki

agnetic orientations or physically damage the plates the data is lost forever.
 Now we're getting somewhere!  
physiclly damaging the plates, I mean really damaging them. Opening the drive and taking a hammer to the plates or drilling holes throu
Just to note, when I mentioned
 gh them, or shredding them into tiny strips, you get the idea. That takes
possible, the ones going one direction of polarization represents 0's while the ones going the other way are 1's.. so as long as the original magnetic orientations are the same, generally someone can recover a block of data. However, if something were to scramble those
m time too... even if you have the hard drive out of the case and easily accessable and have a 15 pound sledge hammer next to your desk and are capable of crushing the drive into a paper thin wafer in one shot it still isnt going to be enough time to execute your data destroying moves if that hollywood door busting scenario were to take place.  So heres my little setup. create a powerful electromagnet and attach it to the drive or around it. Hook up said magnets power source to a panic button. Ok, so it sounds like a pretty bad ass James Bond type setup, but how do I do that?  
s magnetized. Remember though, the magnetic field is only there as long as the juice is flowing. Also know that in this particular case, we're going to use A
First off, you have to create the electromagnet. Actually, logic insists you learn at least the basics behind electromagnets before you attempt to build one.  Whats an electromagnet? Its based on the fact that if you run electric current through a wire, you create a magnetic field. Pretty much all an electromagnet consists of is a core (for example an iron nail) some insulated copper wire wrapped around the core, and that wire attached to a battery. what happens is electrons go from the negative side of the battery to the positive side through the wire.  In doing so, the core
iC in leiu of DC.  Heres a parts list as well as some things you should know about each part:  Wire: solid copper wire is ideal, as it can handle the most current within economic reason. the more wire, the stronger the magnetic field. the further the wire is from the core, the less effective. the wire must be insulated, or it can short and do nothing. wire must be coiled around core in same direction (current must go in one direction @ time)  core: must be made of material able to hold a magnetitic charge. the thicker the core, the stronger the magnetic field (the core is what becomes the magnet) a 'soft' iron core is ideal.  current: 
nt, resulting in greater magnetism to a small degree.
We're gonna use AC, due to te fact that we want to increase the voltage easily and also @ 60hz, AC reverses direction 60 times per second, meaning polarity reverses 60 times a second. Remember when I said that as long as the original magnetic orientations are the same the drives data can be recovered? Well, switching the polarity 60 times a second is going to fix that. Also: the more the current, the more heat generated expodentially. (x^2) ex. you run 1.2V and record the heat. 2x current = 4x heat 3x current = 9x heat 4x current = 16x heat  heat can melt insulation of wire... but by then the deeds done. heat can soften core to an ext
