Plex Media Manager sees external NTFS drive but doesn't see directories

I'm running Plex Media Server. All my media files are on an external NTFS drive. The external drive mounts, I can browse the files in it, Plex Media Manager can see the external USB drive, but Plex Media Manager doesn't see any of the directories or files inside the external NTFS drive. I know others have asked this question before. I even found a solution on here earlier today just before I reconfigured my machine and lost my web history and now I can't find it. Please help.

Solution 1:

Press ctrl+alt+t to open a terminal

Add Plex user to the plugdev group by entering "sudo gpasswd -a plex plugdev'"

right-click your external drive in the directory browser and go to properties to get its location

in the terminal enter "sudo chmod 777 "external drive location; ie media/computername"

right-click your Plex media folder on your external drive and copy the location

In the terminal enter "sudo chmod -R 777 "Plex media folder location; ie media/computername/ntfsdrivevolumename"

Call your ISP and have them help you turn on port forwarding to 32400 in your router. It's not that hard

If you can see your NTFS drive in your launcher it's already mounted. Ignore all the "tech help" telling you how to mount your NTFS drive.
