I tried to connect my WD with an other adapter cuz i forgot my other one at school. Im almost sure this one was 12 volt and after that i inserted my usb 2.0 and my WD started flickering really strange (not because of inactivity)
When i put the USB Out of it it stopped than i put on the on/off button and it normally started up without flickering.
I hope you guys can help me on how to solve this problem
Thanx in advance
