Everybody who owns a computer will someday need to dispose of a disk drive. Before you do, it is a good idea to cleanse the drive, so no one can read your sensitive information. Deleting files and reformatting is not sufficient; determined effort can still reveal data from a drive even after it appears to be gone. To do a more thorough job, I suggest using wipe.

Ah cool. I'll try that next time I need to nuke a sensitive dir (working at a college sometimes I need to carry around info that should really be shredded when I'm done with it).
> I find dban from a livecd (SystemRescueCD of course for me) to be quite easy.

For wiping a whole disk, dban is the cat's meow.

The only better method I've found is using the drive for target practice with a good rifle.
"The only better method I've found is using the drive for target practice with a good rifle."

Not only better,but lots more fun.

Or a bad rifle. I've got an SKS that has trouble hitting an NRA standard target at 200 yards.

Not the bulls-eye, the _target_ itself.

I put up a sheet of plywood at about 20 yards once, with a sheet of white paper stapled to it to see what was going on. There was a perfect profile of a boat-tailed bullet in the paper, so the slugs are tumbling out. Haven't shot it since.

But oh boy what it would do to disk platters at 10 yards!
Bob I have a Smith&Wesson 500 (.50 cal magnum handgun for the unitiated) and a bad HD you could try it out on if you should ever find yourself in my area. Doubtful being that I live on the west coast of Alaska, but even so, it would be interesting to see what a 440 gr slug would do to an old 40 gig HD.

Oooo! The author of _Unintended Consequences_ (great book) makes custom S&W500's.

Of course, I have no money.

This issue of The Libertarian Enterprise might be of interest: http://www.ncc-1776.org/tle2008/tle467-20080511.html
You guys ....

I'm worried that some do-gooder may try to protect innocent hard drives from your mischief.

I think we need an amendement to the Constitution protecting your right to own guns...

Oh, wait!!!!
Constitution schmonstitution.

You put something like that in writing, folks will start to think the paper grants them permission. Permission that can then be taken away.

Oh, wait!!!!

But seriously, all the right to "own" in the world doesn't mean squat if I can't actually shoot the darned thing. "Noise" ordinances... I'll show them the meaning of "ordnance"....

Careful, you don't want to give them ammunition.
Why not? Brass and gunpowder might be considered closed source, but the lead surely is open source and should be shared ... rapidly.
Is this thread really about guns?

Because if it is..its on the wrong website..
> hIs this thread really about guns?

Only in reference to destroying data on hard drives, Scott. :)
And even if it isn't the easiest way... it sher is fun! ;-) ;-)
And for your information, my distro of choice is called weatherby 460.

Once I became a Mac Bolan Fan, I HAD to have one....

Uh, linux distro Weatherby 460 that is.

Funny, we have at work an annual requirement for computer/data security training. Because some of the stuff is classified material, and we are allowed to move it around on thumb drives. Once a thumbdrive that has been used to transport classified data is no longer needed (i.e. the designated classified thumbdrive that is otherwise kept locked up) it must be destroyed.

When I asked the boss if I could whip up a small batch of thermite for said destruction he asked for the recipe. I don't think I'll mention my $2.99 recipe for contact explosives to him.

See Scott, off of guns, back to the really destructive stuff. Ah, the wonders of having a father who was Special Forces.
Wow. Isn't State Securitad..., I mean Homeland inSecurity, making that kind of stuff difficult to get through the chemical supply companies?

I discovered in my youthful experimentation that home-made black powder does really interesting things if you add too much sulphur...

That $2.99 recipe is something I would really like to know. Oh well.

Hey, if heat destroys magnetism (highschool physics taught me something, I guess), how about just throwing the disk drives into a wood fire for a few hours? The Yule Log could do double duty.

Blowing up hard drives..

I have to admit, sounds like a good time.

All we need is a few beers and then we would be blowing each other up.

LOL!!
Finally you'll get to use my favorite epitaph:

"Hey, watch this!"
