Hard shipped by Amazon and received quickly. Packaging unsatisfactory for an object of that type. After installing my turn, it wants nothing to do, you can not install the system above. As a secondary disk, Windows tells me a severe error. The western digital diagnostic tool is not reassuring ... SMART FAIL, disc unusable. This is what happens when we want to close our eyes to all the negative reviews on this hard drive .... Immediately received immediately returned and refund request performed because no disc replacement in stock (about 5 weeks of delays).
