Uh... no such tool. If the data is VERY sensitive, physical
destruction of the media is recommended. Anything else
that can do it "fast" will likely end up doing enough
damage that you might as well be sure and go all the way.
Alternatively, you can go the slow route and make 5
passes over the data writing randomly.

Don't you wish you'd done your homework challenge before the weekend?

Physical destruction can simply result in pieces which an enemy could
piece together again.
To be really sure about magnetic media, they need to be heated to
slightly above their Curie point for a few minutes. The necessary ovens
are not easy to come by.

The experts (eg, Darik) recommend at least 17 passes to make decently
sure.

But physical destruction does come in many forms... and I dare say
that if the number of "pieces" is over a thousand, it's highly unlikely
that the reassemble process will be feasible (how do you know you have
ALL of the pieces... and I doubt anyone could make sense of it all).

Yep.. regardless.. it's going to be REALLY slow. Physical destruction
is the safest/fastest. Since the "experts" are now saying 17 passes (up
from what it was just a few years ago), I'd say the "wipe" technique
is too error prone to satisfy a safety/security requirement.

You could technically double the magnetic head voltage for a 2 pass wipe
and effectively destroy all previous data. That's IF you could do that.

On modern Linux, shred or srm are tools I know. They are not fast at
all. It will take hours. srm comes in source form from some haxor
website. You probably already have shred if you are running suse. Just
do a few passes, I wouldn't bother with 30 passes myself.
I agree with another poster. If you want fast, write zeros with dd. In
'ancient' times they could examine the area of the platter surrounding a
bit to read what a bit's value used to be. I really wonder how easy this
is on a modern hard drive. I suspect possible but implausible.
Also there is some nuke-boot-disk project. Can't remember exact name. ah
here it is: [url]http://dban.sourceforge.net/[/url]

Radial, deep scratches placed on both sides of each platter would
pretty much guarantee that no data will get recovered. This, of course,
would be after wiping apps passed over the platters a few times.
Shredders also work pretty sell. I am not referring to office
appliance paper shredders.

Torch em to a molten puddle, with armed Marines watching worked pretty
well for us.

Write zeros with dd then load it up with porn and they won't find
anything else.

They'll claim that it is all child porn and take your **** anyway.

From their pages:
DBAN supports all unix platforms and securely destroys ReiserFS, EXT,
and UFS filesystems.
Why mention file systems?
Also there are others out there:

And from the governement themselves:

DOH! Send to fast. :-/
I just wanted to mention that you can either have fast or secure DOD
wipes. Both will not be possible if you want to keep the HD alive.
Espeicaly on large HDs this will take a LOT of time. If you have only
one PC, dban might not be the right choice, because it will occupy your
PC without the ability to use it for anything else.
There also is 'shred'.
[url]http://www.fsckin.com/2008/01/09/using-shred-to-wipe-hard-drives-dod-uses-it-you-should-too/[/url]
tells it take 26 minutes for 2GB
And obviously doing a search will give a LOT of other results as well.

Because some are more "retentive" and require a more in depth wiping
algorithm? That makes mentioning file system compatibilities a selling
feature, expanding one's available customer base potential.[color=blue]

Ok Ive done this a few times and it works ...if you know a welder have him
wrap his positve cable about the hard drive several times then weld away.
Gaurantee you that nothing survives the magnetic flux that is created.

ps this destroys the drive and everything on it

Ahhhh... bull****!
I am sure that someone has told you by now that top posting in Usenet
is retarded. This ain't email.
