Best solution fzabkar a c 198 G Storage November 27, 2012 9:39:36 PM WD's forums are full of people reporting physical connection issues with the USB connector. Could it be that there is a break at one or both of the USB 2.0 Data+ or Data- pins? http://pinoutsguide.com/Slots/usb_3_0_connector_pinout.... http://pinoutsguide.com/PortableDevices/micro_usb_3_con... ELMO_2006 a b G Storage November 27, 2012 10:13:12 PM From what I read and heard WD has used plastic connectors that tend to loosen or break if disconnected/connected from the housing. Who knows really what happened unless someone cracks open the case which in turns voids the warranty and you are SOL! pranavburnwal November 28, 2012 12:17:03 PM Best answer selected by pranavburnwal.
