I’ve just an vague answer from WD, here’s what they say:
"Thank you for contacting Western Digital Customer Service and Support. My name is [delete]
I have a few questions about this issue. Are you plugging your product’s A/C adapter into a power strip or directly into a wall socket? If you are using a power strip or battery backup then we recommend that you connect your hard drive directly into a wall socket. In the past, we have seen several customers who have had issues using power strips and battery backup devices.
What happens if you plug the drive into a different A/C outlet at your location? Test the adapter with a voltmeter.
If you have any further questions, please reply to this email and we will be happy to assist you further."
YEAH RIGHT… HOW COME MY AC RYAN, And ANOTHER CHINA MADE MEDIA PLAYER WORKS FINE?? I GUESS THEY ALSO DONT KNOW THE ANSWER. I JUST WANT TO KNOW IF THIS PROBLEM IS FIRMWARE OR PRODUCT DEFECT. I HOPE I DONT HAVE TO PRY OPEN THE UNIT JUST TO UNPLUG THE POWER BUTTON.
