n00b question about something like TrueCrypt:
I'd love to try out some of the features, like a "fake" clean windows install in case anybody boots my computer without me using the right key or something, with the "real" install that I use encrypted and hidden. But it seems the best way to set that up would be from a fresh format. Is it possible/recommended to start with a drive that already has data on it or would TrueCrypt be most effective/clean starting with a newly formatted drive?
