1, You can keep your files on the external HDD(s) just as you would on internal HDDs or on a NAS. The only requirement is they mount (/etc/fstab) before PMS starts.
- The method you use is to create a “TV” directory containing all your series.
/hdd/
tv/
Star Trek (1966)/
season 1/
episodes here
Another Series/
Season 1/
Another Series - S01E01 - title.ext
Another Series - S01E02 - title.ext
Repeat the structure as often as needed
Sections are created and point to the TOP level → /hdd/tv (in this case)
They are a group of series stored in a folder (or multiple folders)
I have
- /nas/tv, /nas/tv2, (as main tv);
- /nas/tv3 is for cartoons,
- /nas/tv4 is for cooking programs
It’s really flexible.
If you need help mounting external drives, there is a how-to (shows you step-by-step)
