Product compliant, only problem is on the manufacturer's website, you can not register the product, suddenly no guarantee that just 3 years 1 year Amazon. After checking the serial number, product "outside the region" ... I'm willing to take that kind of risk, but only if the know before buying, the seller should have clear in its proposal for sale. The origin of the product is USA, the guarantee is valid in the US. I do not know if WD accept the return to the US in case of a problem but the cost will probably go back prohibitive. The seller it is in the United Kingdom, I thought the warranted product for Europe. Hopefully the product is reliable, it is a great brand recognized and acclaimed so it will have to do it ... Fingers crossed !!!
