WD My Book 2TB not working when USB connected to my HDTV

When I connect my Western Digital My Book 2TB For Mac to my TV via USB, it spends a view seconds “loading USB…” but then it just stops and nothing happens. It hasn’t loaded, and I can’t access it via the TV menu options.
I had a WD 1TB (not specifically for Mac - it works on both Mac and PC), and when I connected it to my TV there was no problem at all.

I went through all the trouble-shooting on the WD settings, and according to my computer it’s working fine. It just doesn’t load on my TV.

Any thoughts? 

What format is the drive that works possibly FAT32?  I assume the new driuve is factory formated for Mac. That may be the problem.

I followed the directions on this page -  http://wdc.custhelp.com/app/answers/detail/a_id/291

And it seems to be working now.

Thank you!
