Plex cannot access media folders on Raspberry Pi 400

Server Version#: 1.42.2.10156

Recently installed Plex on my Raspberry Pi 400 station. Install and setup gave me no issues. When it came time to add my media folders, it did not see the folders on my external WD Book drive. The drive itself is seen with no issues outside Plex. I looked and saw it may have been a permissions issue with the dive so I adjusted the permissions using the following:

  • Change ownership to your user (e.g., pi): sudo chown -R pi:pi /path/to/your/media.

  • Set directory permissions (read/execute for all): sudo find /path/to/your/media -type d -exec chmod 755 {} \;.

  • Set file permissions (read for all): sudo find /path/to/your/media -type f -exec chmod 644 {} \;

No errors when running the commands. When I restarted the Plex service and tried again I still do not see the media folders within the Media drive to select from.

I hope that I am simply missing something small at this stage and any help is appreciated.

Thanks.

When mounting drives, you must remember

  1. Make the mount-directory permissions 755 BEFORE mounting so PMS and other users can traverse it.
  2. After mounting, then the chmod again (as you showed… confirming down the entire directory tree into the media)
