I have the same problem. The first time and second time I used it worked fine. I added more media files connected it and it wouldn’t recognise it. I ran the diagnositcs and it showed the passport elite HD driver failed. I purchased My Book Elite loaded the media files, plugged it in, nothing won’t recognise it.
Can’t up grade the firmware either.
I took a cheap USB device downloaded one movie on it connected it…I had no problem.
