WD TV live having trouble recognizing WD-2TB-USB2 but not WD-3TB-USB3

The last thing I would like to add is that my 2TB drive is nearly full (not the case with my 3TB drive) and has those 4 LED lights on the case indicating space usage.  These LEDs don’t light up when I connect the drive to the TV live (contrary to what happens when I connect it to my PC).  They only light up when I disconnect the drive from the PC and connect it to the TV live.  If the drive is not connected to the PC before (say from cold start), then the LEDs don’t light up.  But still this does not appear to affect recognition of the drive by the TV live.

And lastly, the only other difference between the two drives, which I see when I connect them to my PC, is that the 2TB shows up as 2 devices (drive and virtual CD with Smartware) whereas the 3TB drive shows only as a drive. Not sure if this affects recognition by the TV live, and if so, how can I resolve it.

I am desperate for a solution…
