Security is a word that seems to be on the tips of everyone’s tongue these days. With so many hackers, trojans, spybots most people are concered about security primarily when connected to the internet. But with rising amounts of ID theft and the ever-present threat of theft, how do you keep your data safe when you aren’t there to protect it?
So if your hard drive has just been borked after some heavy use, or you just want to trash your system and make sure nobody will ever get their dirty hands on your stuff, you need a surefire way of destroying all your data on that little disk! Without further ado, let’s look into how you can totally destroy your hard drive and everything on it!
NB: Kids, do not try this at home! We will not be held responsible.
- Hydrochloric (Muriatic) Acid Burn
This stuff is highly toxic, so you have to be fully prepared to use it and wear all the safety equipment of the day (eye goggles, aci-resistant gloves etc). To destroy your hard drive using this method you will need to pour in a measure of Hydrochloric Acid into a glass cylinder that is deep enough to avoid spilling over once the hard drive is inserted. Tie some wire around your hard drive case and lower it into the acid. Let it sit there for a number of hours so that the acid gets all the way inside the casing and can munch away on yor disk. To really get the reaction going, expose the acid to sunlight. Be warned, once the reaction gets going the acid will start bubbling and may spill over onto the floor. So make sure you are well prepared! - Burn It With Thermite
Thermite burns at about 3,000° and is used by the military for thermite grenades, making it an ideal candidate to destroy any hard drive. Once you manage to get your hands on some of this stuff, place about 4 or 5 pounds of it on top of your hard drive. It would be advisable to place the drive on sand so that the surrounding area does not go up in flames. Stand far back and ignite the thermite. Once you are satisfied that the drive has been irreparable destroyed, douse the flames in sand or water. - Smash It With A Hammer And Hacksaw
This way is a little less corrosive or explosive, but it will still destroy your hard drive. It also means that you don’t need to worry about where you’ll get some acid or thermite, just have a look in your garage. First off, take a large hammer and start to whack the hard drive repeatedly until you see plenty of damage. Ideally part will be falling out at this stage, if they aren’t give it a few more solid whacks. Then clamp the hammered hard drive tight with a vice. Now take your hacksaw and start to saw the hard drive into fine strips, making sure to wreck the discs and platters. Once done nobody will get a thing off it. - Grind It To Powder
This is another simple way of totally destroying your hard drive, making it impossible for even the best of data recovery services to recovery a single byte. Take your hard drive and place it into a vice, then clamp securely. This clamp should be attched to a large study workdesk that won’t move. Then take a grinder with a large 60 grit sanding disk and go to work on the hard drive. Your aim should be to reduce the hard drive to a pile of powder, just like something you’d see your mum grinding in a mortar and pestle. - Fully Bork It With Magnetic Degaussing
Finding magnets powerful enough to magnetically degauss your hard drive will be a bit of a challenge, but it is a foolproof way of destroying any and all data on your hard drive. Once you get your magnets together, lay them out on a surface and pass your hard drive over them. Rub them back and forward, left and right, alternating exposure to the magnets.
The basic premise of each method of data destruction is to destroy the disc and the platters, otherwise data can be recovered. When engaging in an act of data destruction, make sure and target these 2 areas.
I haven’t included any software as a lot of these software-based data erasing products will actually leave something behind. If I wanted to destroy my data, what use would that be?

[...] This may be an indirect way to save money, but it is worth the effort regardless. Back up your data weekly or even on a daily basis if you are a heavy user. This means that if you do destroy your hard drive you’ll not need to pay for an expensive data recovery. [...]

Hello,
I have a 5 year old gateway computer. pentium 4, 128 ram, 20 gig. the original wd200 hard rive seems to have gone bad and I replaced it with a 40 gig wd400bb caviar drive. Now as soon as I power on the computer I get a black screen with that reads “A problem with the hard drive has been detected. consult troubleshooter setion oy your owners manual. Press the enter key to continue.” I press the enter key and the computer boots up fine and everything seems to be working. The bios shows the drive detected correctly from what I can tell. Any help is appreciated. Thank you, Bob

a simpler way to destroy your hard disk is to just install windows

I agree with the money saving guy. I bought one of those bare IDE hard drive USB 2.0 adapters to use all my old hard drives as redundant back up devices along with DVD-R discs.

Hi Andy,
I’m a girl. I have a hammer but not a hacksaw. All other ways of destroying my hard drive(s) seem too hard (no pun intended). I’ve got several of them I’ve pulled from all my old computers and I’m ready to let them go, because they are heavy and a pain in the kiester to pack and move around for no good reason whatsoever except I don’t want some resourceful person to hack in and get my vitals…
Would simply giving it a bubble bath help to destroy it or is acid necessary? Beach bonfire maybe? Would a dip in the ocean and sunning maybe help to corrode and rust the apparatus?
Do you know if there is somewhere I can take my hard drives and have them destroy it in front of me? I mean, I’d happily pay for them to be destroyed for me. To think I could hammer it to death and still not get it because of no hacksaw? Plus, I’m strong, but those buggers are hard and I don’t know that I’ve got the braun to do it…

water probably will not destroy the data itself…. just beat the living shit out of it until it looks borked enough….. THEN dip it on the ocean… THEN throw it in a fire.

Drill holes in the drive. Make sure you go through all the platters inside the drive. You have to make sure that the platters are destroyed (not just outside enclosure) since that is where the data is stored.

I’ve often wondered if it’s possible to implement some sort of slef destruct mechanism. For instance, if I wanted to destroy all the data I had on say 4 disks in one computer. I wonder if it’s possible to build some sort of electromagnetic pulse generator thingy. Just one button and *boom* all data (and probably all electronic article in the room, if not the house) destroyed.
I wonder…

LOL … or a handy magnetic type gadget thing like they use in the movies.
I believe the geek in The Core had such a device.

If you have a volcano nearby, you could always toss it into the crater. Afterall, you can never be too sure. =D

It’s not necessary to kill yourself trying to destroy the casing. Just open that sucker up and destroy the platters with the grinding method. You don’t need a grinder, you can use just your hand. Also acids hurt when they touch you, I’d stay clear.
It wouldn’t be a bad idea to destroy the circuit board. All you have to do is put some current through it. DC at least 100v will fry them up. But wear rubber gloves and maybe a long sleeve non conductive shirt when doing that.
Good luck or just get some m80’s and let er blow!

I am surprised nobody has mentioned degaussing.
You can take a hand held Video/Casette-Tape Eraser (basically an electromagnet) and magnetically trash the drive’s data.

I saw a movie in which a hacker was about to have his apartment raided and heard them trying to bang down the door so he quickly ejected all his hardrives and put them in the microwave on full power. How effective would this be at making the data unrecoverable and how long would it take?
17 Kes // Aug 22, 2008 at 7:05 pm
That would be a scene from “The Core.” Those were not hard drives either. Those were Cd’s, and a microwave is very effective at destroying Cd’s. Put a hardrive in the mic, and good chance the platter will survive, as the microwave will probably blow up before it gets through the casing. And in the core, he had high powered magnets very sufficient for the job as he was prepared for people to come raiding his apartment. Wont find something like that in a store. Mythbuster guys had a hard time getting there hands on some high powered magnets. Had to prove the company that makes em 100% who they were before they could get them.

Actualy magnets from the hard drives are pretty powerful. I didn’t thry it my self, but i think that could work.
19 Shred It // Sep 9, 2008 at 4:41 am
You can try shredding it in one of those industrial shredders that will shred it to tiny pieces, but first take out the magnets – they are sweet!
