    I just got to thinking about something.
    We all know there are programs like diskwipe which overwrite your deleted files, and there are encryption programs like Truecrypt to do encryption.

    Is there any combination of the two? Something that, for example, would wipe the unused part of a disk and simultaneously leave random data behind? And then to follow that, something (perhaps livecd) which would take a password, then write your encrypted data on the "empty space" on the disk? And stealthy, so that, without knowing the password, the encypted data/filesystem would be indistinguishable from just random characters?

    That way, if you are asked to provide a password to the data, you could just say it was random bytes left by a wipe, and the authorities would be unable to prove differently?

    Obviously, once you started using the "empty" space on the disk for encrypted info, you couldn't go back and make changes to the "official" file structure, since it would unknowingly overwrite your encrypted information, but you would have the plausible deniability you need in order to withhold a password.

    Any thoughts, or have I explained it well enough?

    Or does truecrypt already do something like that? And if so, why would you not just be able to deny the empty partition (or part of a partition) was truecrypt encrypted?

    ok, it sort of looks like "hidden volume" in truecrypt does this. So the random write to deleted files is kind of unimportant. Thanks
