I should have known better and follow the comments of some. Out 2 weeks after installation. Fortunately I had a clone .... Avoid absolutely That was my comment there a while. There are 2 or 3 weeks, I bought another HDD at Amazon happened down. Normal: cardboard packaging without any form of protection !!! despite dozens of buyers comments. Congratulations Amazon ... Back at Amazon for a refund. I then bought out my hard drive at the time at Nord Gmbh PC and invoice. I log on Western Digital to seek application of the guarantee. The WD website says that the date has passed (even before the date of my purchase ...!). I leave an email to contest. 5 days after they recontacteront me to ask my bill. Meanwhile, I write my seller asking him to enforce the guarantee. The next morning, I received a very nice email from the seller asking me to redirect their hard drive to look after the warranty. I ship, wondering if I was going to bilk (for these times, scammers abound ...). 10 days later, I received a new disc, very well packaged and protected. It works well (for now). Finally, I do not know what note to this disc, but certainly I put 5 * seller Nord Gmbh PC, honesty model. The next time I have to buy a hard drive, I will first see in his shop, and even if the price is a few euros more expensive, I would not hesitate to place their order.
