Have exhausted my limited skillset - Need help getting media server to see second HD

Hi all, I've spent hours upon hours trying to figure this out. I have a second mounted HD with all my media files stored (Formatted ext 4) No matter what I do, I can't get Emby(Or Plex)to see any files on the mounted drive.

I've edited Fstab, and i've set the drive to auto mount, but I can't seem to get beyond that.

Thanks in advance for any help/education guidance. I've attached a few screens, and sorry if I've done something really dumb, or if this is in the wrong place. You guys and gals rock!
