I recently got my laptop stolen with some sensitive informations on it (personal source code, bank details in a secure file, passwords, etc) and I learnt the lesson: encrypt your sensitive data. Now, I am wondering what are the options to encrypt a partition (not an encrypt disk image) ?
Aim: The aim is to prevent anyone (except me) to access those data.
Requirement 0: The software must be able to encrypt non system partition.
Requirement 1: Plausible deniability is required but preventing cold boot attack is however not an absolute requirement (I am not famous enough or have sensitive enough info to have this kind of requirement).
Requirement 2 : Software taking advantage of AES hardware encryption are very welcome as I intent to get a Macbook Pro with i7 CPU (with AES-NI enabled instructions). I will have avirtual machine running in the encrypted partition.
Requirement 3 : Free or reasonably cheap.
Requirement 4 : Software must run on Mac OS X Snow Leopard or Lion.
So far, TrueCrypt is the only option I have found.
