WDTV won't recognize external HDD suddenly

I’ve had my WDTV Live player since January.  Since the, I’ve had a Hitachi 2tb external HDD attached to it to stream movies.

Today, I watched a bit of a movie, stopped, turned off the player and came back to it later.

When returning, the player only recognizes one of my 2 HDDs but not the Hitachi.

I have tried updating firmware, resetting the device.  Ejecting the HDD it did recognize, tried the Hitachi in both ports.

I also plugged the Hitachi into my PC and deleted the wdtv folder.  When I plug the HDD into my PC, I can see my files.

Any ideas?

You may try moving the files from the Hitachi to another location, reformat the drive and retry.
