If files are moved to the Missing Files page, their events and tags should be preserved inside Shotwell. I attempted to reproduce this but couldn't.
How is the hard drive mounted (USB, network, etc.)? Is the hard drive selected as your library directory (Edit -> Preferences)? Or are you referring to the hard drive via a symlink on your local filesystem?
