There’s another solution, one that works with whole-disk encryption products like PGP Disk (I’m on PGP’s advisory board), TrueCrypt, and BitLocker: Encrypt the data to a key you don’t know.
It sounds crazy, but stay with me. Caveat: Don’t try this at home if you’re not very familiar with whatever encryption product you’re using. Failure results in a bricked computer. Don’t blame me.
