Physically destroying hard drive data

Turn the drives upside down and give one good wack with a 3lb hammer. I bet
you could one every two seconds. Ya can't reload that fast.


75 round drum magazine, an aimed shot per second at least. ;)

Besides, whacking them with a hammer does nothing to destroy the
platters themselves.

Ok so maybe I just want to find a use for shooting stuff...

How about just scratching all the surface of the platters, I don't see
how anyone can retrieve anything after that. Acid and melting them are
two good ideas too. Or take the platters put em on the floor and stomp
on them yelling GO AWAY DATA AND DONT COME BACK!

I'd be very surprised if any .30 caliber firearm on the market was incapable
of penetrating completely through a disk drive.

I agree, it can't take much energy to blow through a hard drive, anything in
30 cal should do the job nicely. Plus it would be entertaining! It doesn't
get much easier than shooting the drives, if you are already a shooting
enthusiast and are going to be shooting anyway. A couple more points:

1. Any decent wiping software should have no trouble eliminating data, as
was mentioned earlier. Time consuming yes, I choose physical damage myself,
usually in the form of a big hammer or other heavy object.

2. If its really just CC numbers, bank info and such, almost anything
destructive you do to the drive is going to require more effort than any
common thief is willing to shell out. Plus, any thief with that kind of
skills and ability is likely much more particular about his targets. He's
not after small potatoes.

3. If its the government you are worried about, well, by the time the feds
are on your case so much they are recovering your old hard drives, I think
you are pretty much screwed anyway.

Take a hammer of a respectable size. The platters will at least be
bent, and they'll have a big impact mark.

Far easier: Open the HDD, remove the platters and just bend them.

What exactly makes you think you can bend them.
That makes it already extremely expensive

Bending them? Probably.
and maybe impossible for most practical purposes to recover anything.

And probably much cheaper if you just shatter them.
Or do nothing since refitting them and getting them
to work again is probably extremely expensive too.
If you are worried enough you can also blowtorch the platters, which
makes recovery completely impossible (in the physically strong sense),
since above a certain temperature the magnetisation is completely and
irretrivably lost.

Not opening the disk is risky, since you actually may fail to damage
all platters, even with the .30 bullets.

And now babble mouth is a gun expert too.

You're just not using a big enough hammer.

Build a small trebuchet and use them for shotgun practice. Good excuse for
building a trebuchet. Just don't get carried away--you don't need one big
enough to sling a house.

I've seen pictures of bent platters, our stupid spooks got all excited about
what they claimed was high security stolen info on a journalist's system.

Not a pretty sight.

Fraid not.

Bit hard shatter metal, stupid.

For a really through destruction, just nuke them. Anything that
somehow survives the intense heat of nuclear blasts are likely to be
wiped clean by the electromagnetic discharge.

It's very easy to tell, the bullets go all the way through and you
can see the platters penetrated, bent, and partially sticking out
through the exit hole. I've got pics somewhere from a long time ago
when I tried it.

I had the opportunity not long back of shooting up some old HDDs,
mostly in the sub 1GB range. We shot them with quite an assortment of
guns, and it's safe to say that pretty much any modern centerfire
rifle cartridge and any handgun cartridge over .38 caliber will damage
a HD to the point that only high-power spooks can get your data off,
and I'd have my doubts about that. Shotgun slugs would be effective
too, but I'd be concerned about birdshot or buckshot unless you're
very close.

We did compare the effects of a .223 rifle (Keltec SU16) and a .357
magnum revolver (S&W 586 6"). The .223 punched a neat hole in one
side, dished both platters, and stayed in the dent in the first
platter. The case was not deformed much. The .357 punched a much
larger hole, mangled both platters, and exited the back side, leaving
the case resembling a jagged potato chip. A Weatherby .300 magnum
trashed them the most thoroughly, but it's a bit expensive to shoot.

It was fun, but when I need to destroy a pile of HDs, I take a 3 lb
drilling hammer (like a mini sledge hammer) and whack them until
they're bent - usually 3-4 whacks - then throw them in the trash.
This is far faster than anything else I've tried, particularly
anything that involves opening the case. It's less fun than shooting
them, but I have to drive a few hours to be able to shoot drives. If
I could shoot them in my back yard, that would be my choice.

O.k., if you can visually tell all the platters have been damaged,
that would be fine too. Shooting HDDs is not really an option
here. Getting a weapon you can actually shoot when you like is
difficult.

Well, let's see how you bend the glass substrate platters from
an IBM DTLA or later, or a Maxtor DiamondMax Plus, shall we.
Bit hard shatter metal, stupid.

Very easy when of metal ceramics. Or glass substrate.
Impossible to bend, that stuff.

You have heard of glass substrate haven't you, clueless?

Pity the old obsolete drives he's talking about

Right, when drives didn't yet have glass substrate platters.

And even someone as stupid as you should have noticed
that glass doesnt survive bullets too well, ****wit.

The first glass substrate plattered drives are 5+ years
old now and "well past their useby date", clueless.

But only someone as clueless as you will think that shattered
glass will be partially sticking out through the exit hole.
