Its magically back today. It was in fact a Windows partition I was seeing, D drive is disk 2. But today its back like nothing ever happened. And i did restart my computer and turn it all the way and then back on last night with no change. Now Steam isnt recognizing the games on it and is still asking to install instead of launch them. I can ope the drive and see the game files there tho.
