Pure speculation here, but couldn't you keep a sufficiently powerful magnet in your house and just throw it on your hard drive if/when the police/mafia/your parents come in to break down the door?
Yes but you need a very big magnet for that to work. Also it does require you to pull that HD from your machine which many do not have easily accessible. ie. Most people can't just open their computer case & take out the hard drive in a few seconds.
Best way if you are real short on time to to have the computer pre-wired to just blow up (ie. explosives on the hard drive) but even then I'm not sure you can be certain you have destroyed the dics (physically) enough. Plus would that not mean you have destroyed the evidence?
Seems like the double encryption would be the way to go.
So.... you admit that the drive was encrypted with a 25 digit password?
Seems to me it would be better if you just SHUT UP.
He does not have to say anything about the drive being encrypted or not. Anyone with PC skills will know when they get a drive if it's encrypted or not. That is not the issue. The issue is getting the drive decrypted if you don't have the password and it's a freaking long 25+ one that is many of characters (ie. not something you find in the dictionary but something that makes no sense. ie: dssu76723A*$3=-.,Jhgrt7eaj%4rahd)9765=['$32@
