    Hi there, I was wondering if there was a program that asked you for a password each time you turned on your computer. The catch is that if you put in a special "wrong" password, the system will just format everything, just to make data recovery more difficult.

    The issue with that system is that it would have to read-protect the entire drive. Otherwise an attacker could just copy the encrypted data to a new system.

    So you'd basically be making your life a lot harder but an attackers wouldn't really change all that much.

    *Instead* you could get something very similar.

    Encrypt files with password + key file. Store keyfile on an IronKey USB drive. That IronKey USB drive *can* be made to delete all of the info on it.

    Without the keyfile the encrypted container is pretty much dead - you'd have to bruteforce the keyfile + password, which is unrealistic.

    If the IronKey is out of the question you could have a keyfile on your USB, and just hope the attacker doesn't know about it. If you feel your data might be under attack, break the USB or 'lose' it fast.
