No need to reinstall. Copying and pasting the game folder to any HD will still allow it to work just fine in my experience with this game over the past 3 years. I keep all my games on a separate HD and have upgraded the OS several times over the years and those that don't require registry entries to run, like RoF, Il-2, etc. never need to be reinstalled and work just fine. Steam, on the other hand will need to be reinstalled, even if on another HD like I have mine.
