Programs that entirely wipe the disk need to be on their own bootdisks. Their installers typically have you burn a CD-ROM and you boot from that. You'll never be able to entirely wipe the drive if it's running the OS you're using to run the program. Man that is an awkward sentence but that's grammar for ya

DBAN is good, you should be able to find it somewhere, it boots into a little Linux OS and you wipe whatever.


Boot DBAN off a CD, start the disk wiping, and let it alone over night or a couple nights.

do you want to do standard reformat or a extreme reformat were nothing is recoverable

if you want nothing to be recoverable there is

If you want total security, use a hammer to the HD.

Use DBAN.

or a hammer.

or a f*****g big magnet.

Odd.

I type DBAN into google and the first link is dban.org with sourceforge downloads links working as usual.

Try again.

Unless you have a cache of military secrets/kiddie porn anything else is pure overkill.

Correct application of explosives can work wonders on wiping HDs too :P

Not only is the data gone, but this also solves the problem of hardware disposal too. 8)

It's a win/win! There is no possible way that could go wrong :P

Aquire a large bucket, some rare earth magnets, Hammer, Tongs/Gloves and some Hydrochloric acid.

Mix up an acid solution in the bucket.

Add the hard drive.

Add the magnets.

Stir (for best effect use a paint shaker(like they have in hardware stores) to shake the mixture up)

Leave it stand for a couple of days.

Remove the HDD with a pair of full length chemical gloves or some tongs.

Proceed to smash the living S**t out of the disk with a hammer (don't stop till the physical data platter is removed from the casing, if you want rub some of the acid magnets on the actual platter for safety)

Snap the data platter into two pieces, and bury the remains of your hard-drive in separate corners of the world.


Please not this is the only real 100% foolproof method of deleting your data, people can, and will recover data off seemingly "wiped" hard drives.

Eraser is another good application for wiping files anyway. It has options from 35 pass gutman all the way down to british 1 pass baseline and USDoD 3 pass wipe. It can also wipe free space.

Not secure enough. You can still recover information even from that.

Would giving it a bath be better?

You wouldn't have said that if you'd seen the platters. Or rather, what was left of them...

The solution is simple. All you need are the field windings from a car alternator. Never mind the big arse magnet, the field from these without the armature is massive, more than enough to clear any and all data from the hard drive, as well as send a transient spike from the transformer large enough to blow the power coupling capacitor. Just put 12 volts to one of the windings, while holding the cage somewhere within 4 foot of the computer.

Experience counts!!

Stick a label on it saying "This drive blows up PSUs" and leave it on the street.

LOL. You could take apart the drive, expose the internal disks to magnets, then beat it with a hammer. Extra safe. Since the internal disks are very, very delicate. hitting it with a hammer does irrevocable damage. Also, I don't know anyone who can reassemble a hard drive and have it function. Certainly not your average laymen data thieves. Too much trouble for potentially no value at all.

Really, the best way for someone that does not want to get overly complicated or spend any more money on this is to simply take out the HD, and destroy it. Smash it with a hammer, throw it in the fireplace when you have a fire going, etc etc etc. The hammer method is the easiest, just get a hammer and a few nails and open the HD (unscrew the screws) and punch a few holes in it then hit it to bend the disk.

Hope this helps

Do wear eye-protection. Modern disk platters are made from glass or glass-like materials and will shatter.

A single zero-fill or random-fill using dd (dd if=/dev/urandom of=/dev/sdb) or similar Linux utility will overwrite the drive in a way that no normal user can extract any meaningful data. If you are not the target of the FBI or someone with a lot of money and specialist equipment, then overwriting the data is effective.

A simple format, even a low-level format, may leave data (banking details, personal data) on the "free" area of the disk that can be recovered with testdisk, photorec or other tools.
