Wat??? You can only publicly use the data from breaking encryption once. Once the encryption is broken no one use it anymore.

Also do tin foil hats REALLY work?

What about salvaging the degausser out of a good quality monitor, or building your own? Rig it to a capacitor bank and an appropriate switching circuit.
Knock on the door.
Hit the switch.
Capacitor bank sends an EM blast through your hard drive.
Turns out it was only UPS at the door.

It's all in the cost/benefit. Mechanical locks are expensive and difficult to replace, and potentially difficult to attack (in that it requires a physical presence at the site), and only one person can work on one lock at a time. This makes it expensive to resolve a weakness in a deployed system, but at the same time, the risk is more diffuse, as there may be other physical barriers or security measures.
In the case of electronic encryption, the speed at which you can attempt to break it depends only upon the resources you are willing to commit. Similarly, if an encryption technology is demonstrated to be vulnerable, those people with the greatest need for security can deploy something else via software updates.

The only thing that's stopping it from being cracked is computing power. With something like a typical windows / Linux /etc install they can target certain items and reverse code break.
They have some pretty impressive super computers.
The main thing though is no one is really using 256/AES.
That's a very old standard based on old MFM drives - these machines didn't use servo tracking heads, and as a result, the heads could slip out of alignment and result in the zeros being written off center - leaving a strip of old data that could be extracted if the head alignment was then adjusted slightly in a clean room.
In modern servo drives, with their complex PRML storage algorithms, there is virtually no 'slack' space between cylinders or, indeed, enough residual magnetisation after a zero fill to usefully reconstruct such data. Perhaps, it could be reconstructed on a patchwork basis - but it would require custom made controllers, and data processing systems.
I'm not aware of anyone having extracted useful data after a zero fill from a modern drive (multi GB). Indeed, the current teaching in modern computer forensics, is that if the data has been zeroed, it's toast. That's not to say, that recovery compnaies haven't tried and have found data on supposedly zero filled drives - there are a definitely a number of broken zero fill utitilities out there, that can end up missing significant portions of a drive - or perhaps the comp crashed, or rebooted during the zero fill, and the person supervising the fill didn't notice.
Rig something beforehand that would inject a highly corrosive substance directly onto the hd platters at the touch of a button. You'd need your own clean environment to take the drive apart and install the apparatus, but I imagine that you could use some plastic bags and a sealed fishtank or something.

Actually would a plasma cutter work? If the drive is external you pop the external case open take the drive run to your shop, cut it in 4 and just keep cutting until they break into your house. You'd want to have a camera so you can check who's at the door without actually going. If they see you and see that you're not opening up they'll just open fire right there and then but if they just don't hear any response they'll either figure nobody's home or its just taking you long to answer the door.
Though that thermite stuff really sounds like fun.
Another option, though way more expensive is to have a seperate building with a server where you store all your data, then a very regular looking PC that you work from. All you then have to do is disconnect all network drives and hand them the PC. Show a bit of resistance or they'll figure you have something up your sleeve by being too willing to give up that PC.
They'll power on, crack your windows/linux password, log in, and only see what looks like a very normal windows install. Keep a few non personal/confidential photos/documents though so it at least looks like an average PC. To avoid them from recovering stuff like your browser history just do all your browsing through a VNC session on the server. (you could write a script for this and store it on the network drive - deletes all evidence leading to your server, then removes drive).
They may or may not find out from this point that all your stuff is done through a server, but at least it gives you LOT of time to run a shred or what not on the server's drive, without physically destroying it, or you can still physically destroy it. (I'd do both, and trash the pieces over a period of 2 months in different places/garbages)

If the FBI were coming for you they'd do it crack of dawn coming in full force. During the MOD/LOD war this is how MOD was taken in...many still living at home. Chances are in reality you aren't getting 30 secs, you ass is probably getting woken up to a shotgun/M16 in your face.

Don't they at least knock first? lol. That's pretty bad. Glad I'm not in the states, don't have to worry about that stuff. We have the RCMP but they don't really use high powered guns. Would scare their horses away.

It is NOT easy to get all that evidence back... You put it up to a magnet or wipe it with DBAN and you are good to go.
lol...in your quest to sound smart in every topic you enter, you always miss the obvious stuff. You agreed with what he said and then completely contradicted his advice. Nice.

Hm, is there something I'm not getting here or would a fairly strong electromagnet not do the trick? Flip a switch. Data = boned.
Have you tried that? I doubt the microwave electronics can produce enough energy to melt a hard drive in a minute. I imagine you'll ruin the electronics and break the microwave, but not actually kill the platters.
Here's another question. Isn't destruction of evidence a felony, too? How do you make it look like an accident?
And what about just using an encrypted file system. Until a supercomputer is invented, you don't have to worry about someone cracking a modern encryption scheme.
I think there was a court case somewhere that ruled that not giving up an encryption key wasn't protected by the right to remain silent.
Maybe encrypt the disk with a USB key holding the key, and destroy the key when the feds show up.

keep questionable data on CD/DVD. Shatter it to pieces and throw it on the stove i na pot (no water). DONE
