WD Live Connection to external hard drive


I have a WD Live and when I connect it to my WD My Book Essential External 2TB Hard Drive via any USB port, the WD Live freezes.  I doesn’t recognized the the drive and slows it down to a hault.

I just bought both items and have the firmware updated to the latest version.  

Does the hard drive need to be formatted in such a way to make it compatible?  Is there anything I can do to make them compatible with each other?

The USB port works with flash drives.

Hello, Did you check if you can access the my book fine from the PC?
