Can't be recognized by my WD TV HD Media Player

I recently bought My Book Essential 3 TB, to be used on my WD TV HD Media Player… but it cant be recognized… i’m wondering if it’s because that my hard drive is a 3.0 USB? I tried upgrading my Media Player, but i can"t seem to make it work. Is there someone that can help me? Thanks.

   

Depending on the player it might not be supported

the older units support drives up to 2TB

what model and firmware WD TV you have?
