My 6TB Duo Raid1 seemed to work as well as the previous My Book World II, except for this issue:
I cannot stream my Gopro MP4 videos to my XBR-55HX929.
I can stream the video to PC. Also I can throw the video to the TV from my phone with WD2Go but The Sony will not see the video from the new server, while the same file from the My Book World II works fine.
I just received an alert telling me of a drive failure, of course with the Raid1, everything is as I stated above.
