TrueCrypt is good and has been reliable for some considerable time, but
, along with others, not considered 100% effective any longer.
There is some word of it being vulnerable to crack through hibernation
and possible RAM read, although I'm not completely au fait with the
situation as I haven't researched it as yet.

I can highly recommend Scrypt.
I'm not sure of its availability for Windows but if you are running
Debian or other open source software, it's readily available.
It's a simple password-based encryption utility which demonstrates the
scrypt key derivation function. On modern hardware and with default
parameters, the cost of cracking the password on a file encrypted by
scrypt enc is approximately 100 billion times more than the cost of
cracking the same password on a file encrypted by openssl enc; this
means that a five-character password using scrypt is stronger than a
ten-character password using openssl.
Cheers!

David.
