I have tried plugging the My Book directly into the wall socket - makes no difference. Still does not read.
When I use a USB 2 cable and connecct to the My Book USB 3.0 port and my Lenovo it does not read as well. Tried it on my Desktop PC running Window 7 - does not work as well.
See the packaging photo below of the My Book it says “Window 8 compatible” , MAC and Superspeed USB. I suspect it is one of those rush product that the product marketing people at Western Digital push out just to fill up the product line and store shelf in time for X’mas to maximise the billing. You know what they say “store return is somebody else’s problem” especially if it is via a distributor or reseller, the store return only comes back in the next FY. Probably the product has not been rigorously tested for compatibility with Window 8 or USB3.0 Superspeed.
Going to return it to the store for something that works.
