Plex cannot see folders in Volume2

[DigitalAnalog]

Hi - I'm running Plex Media Server on my F4-423 with TOS 5.1. I'm setting up Plex and trying to point to my media folder in Volume 2 but it cannot see the folders inside? I have no problems seeing and accessing these folders anywhere else in the system and in the network. What could be happening?

May be the media user group lacks permissions on the folders and subdirectories of volume 2. Please go to Control Panel - Shared Folders - Set user group permissions to allow media user group access.
