NTFS does not use Linux permissions.
Therefore, the ntfs-3g drivers & packages yield the equivalent of fully open (full access).
If PMS cant read the files , the most common problem is where the drive is mounted.
In Ubuntu, Fedora, and most other systems using Gnome, /media is a reserved directory. As such, anything visible in there is exclusive access to you. User plex will have no access.
Please provide additional details. A good starting point is a df output capture (copy/paste as ‘code’) so we can see what you’re seeing.
