Ok so I have a SSD that I boot up on and has a few things and all of my games and crap are on my HDD but anyways earlier today everything was running fine and I turned off my pc but when I booted it back up almost all of my applications wouldn't work and so I checked to see if the hard drive would show up in the file manager and it wasn't there so I then checked my disk management and my hard drive showed up but as an unknown, I can even hear it running but and I have no idea what to do. Also I have a few pics below (sorry for the bad quality). Thx for reading and any help is appreciated!
