On a removable media, you cannot easily password-protect stuff, as this
relies heavily upon cooperation by the OS that reads the media...

However, you *can* encrypt stuff, so that it can only be read by those
having the correct key/password.

Even when encrypting stuff the challenge remains to choose an encryption
that is both safe enough and available on the reader's OS..  Personally
i'd choose GnuPG unless there is no way it can be used...

Hope this helps

After seeing all the viruses, trojan hourses, worms and Reply mails from
stupidly-configured anti-virus software, I can only conclude that Microsoft is
dangerous to the internet, and it's software should be banned.
