How do I setup my WD ELEMENTS DESKTOP 5tb as SANs

I wonder if anyone know how to set up my WD ELEMENTS DESKTOP 5tb drive as a SANs but connected to my Sagemcom F5260 Router - I would like to set it up where anyone on my WIFI LAN can access videos I have on it or even from the internet

I assume you mean NAS (Network-attached Storage), not SAN (Storage Area Network).

The Elements is just an ordinary hard drive. How to get access to it via your router would be documented with your router.

Woops, dyslexic kicked in. Yes as a NAS.

Sagemcom F5260 Router documentation has instructions but not very detailed - I will persue down that avenue.

Thanks for the reply
