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... | Report abuse Reply to fzabkar ELMO_2006 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! | Report abuse Reply to ELMO_2006 pranavburnwal November 28, 2012 12:17:03 PM Best answer selected by pranavburnwal. | Report abuse Reply to pranavburnwal Register or log in to remove Ask the community Post an answer Tom's Hardware>Forum>Storage>EHD Running in 3.0 but not in 2.0 plain/combo ports> Related ressources: ForumZ77 Extreme4 Intel USB 3.0 ports behave as USB 2.0 ports Forum2x PCIe 2.0 GPU in PCIe 3.0 and 2.0 ports ForumConvert front USB 3.0 ports to 2.0 ?
