How do I put a simple password protection on an external HD? Furthermore, how do I make it so that only other users have to input the password? :$

If you were to create an encrypted DMG on your external and mount it with the password that would be saved to your keychain so would remember it from then on.

That would give you an encrypted drive and only require other users to enter a password.

If you're looking for a pure hardware solution, consider looking at Apricorn drives. I have a 500gb portable drive, with AES-256 encryption and a numeric keypad to enter a pin number. The drive won't mount unless the pin is entered and even if the drive is removed from the enclosure, it's encrypted, so data recovery is virtually impossible. I'm using mine for Time Machine backups, and I love it. I work in an environment that requires full disk encryption of both internal and external drives, and it's been one of the easiest drives to work with that we've tried. No additional driver software required. The 640gb (current base model I believe) is around $130.

TrueCrypt works just fine on my 10.6.6 system, but I can believe it doesnt work on 10.6.7 yet.
