[WLUG] Reconnecting with my media drive

When I was running Debian, I had most of my media segregated on a Seagate SSHD. That's still in the system now that I'm running Mint. I'm trying to get Plex up and running again. The file manager shows the media drive mounted, but shows nothing on it. I don't see it listed in fstab. I don't remember how it was formatted, but I think it's an ext4 drive. What should my next step be? -- Rich
