    I have an external hard drive, formatted GUID, Mac OS X Extended (journaled); Can I lock the drive to require a password to open it?

    If I Get Info, I seem to have the ability to give Staff and Everyone Read & write, Read only or Drop Box access.
    I don't see a way to rquire a password.

    I'm not pretty sure but maybe MacHider could help. Google and download one to try.

    The best way is to just create a password protected disk image in disk utility. It's not locking the actual drive but as far as making sure the information is secure it should work.

    And FileVault. go to System Preferences and find it under Security.

    Also you can try Disk Utility, it's under the Utilities folder. make a New Image and define a capacity and choose AES 128 to add a password. then mount this new .dmg image and copy your private files into it (just like using a USB drive). you can move this .dmg image to anywhere. In this way you will be asked to type in correct password every time you mount this .dmg(not every time you open your external HDD). I recommend this cause it's not possible that every file on your external HDD needs to be protected by password.
