So all you need is encryption in any way (any cipher/hash/keysize combination will do) and a strong enough password or a keyfile on USB memory. No withening of available disk space is necessary. Practically, all you'll have to do is to stick with the defaults and do the encryption. If there's unencrypted data on your free disk space, you'll however have to overwrite it. Just do the encryption, log into your machine and do something like "dd if=/dev/zero of=deleteme".
