my new MyCloud 3TB, worked just fine until today. I watched videos without any problems.
When I logged on to the dashboard, I got an error: USB internal server error (400255), and when I went to other menues, I saw more error popups, so I decided to reboot the NAS. After reboot I cannot log in anymore to the dashboard, and the LED stays white for 1-2 minutes, den it blinks one time, and then it stays white for an another 1-2 minutes.
Now I cant access my files anymore…
and yes I waited an hour but still white led, and also tried to plug the power off and on again, did not helped so far
