What is the latest firmware version for My Book Essential 3.0 wdbacw0020hbk-01?

My Book Essential 3.0 2TB 

P/N: wdbacw0020hbk-01

I tried upgrading the firmware but it says I already have the latest installed which is v1.003. However, on the release notes, the latest version seems to be 1.016. Which is which? 

I hope someone could shed some light on this. thanks!


I had a lot of trouble trying to update my software for My Book Essentials 3TB. Finally, I phoned Western Digial Support Line. A level 2 technicial took control of my computer remotely and spent an hour or two updating the software to Version 1.5.1 if my memory serves me correctly.

1.5 is probably the smartware version, not firmware version.
