I’m having the exact same problem with my USB3.0 My Book Essential 3TB. It runs fine for about 30 minutes and then disappears. I can be streaming a movie from it and then I get a network error on my WD Live TV, go check the computer and the My Book is no longer recognized. This just started happening a few days ago. Never ahd any issues before and I’ve had the drive for 11 months.
Any help would be appreciated!
