Product much worse than the previous generation of my passport essential. The worries: micro USB connection! Why not let the Mini USB connection? Surely to encourage us to buy again and again the cables. I had in my two hands of these discs: the first: Can not connect after 3 cable connections, obliged to buy a micro USB cable that is not found anywhere yet (of course it is found on amazon). The second disc will soon go home amazon because it is recognized by the computer but the formatting will stop at 5% and the disc rotates in space, only the quick format works but it is not fast at all. But the icing on the cake is the data transfer. Impossilbe copy a few mega bytes without it indicates at least 1 copy of hour. The hard drive yet made any noise indicating that let appear a problem writing. So I put this question to the constructor of this wonderful disc malfunctioning why put a Micro USB connection while the mini usb fonctionnai very well on old discs generation? I appeal to the builder for the return of legacy disks. When you plug the drive uses a drive letter for a virtual cd that you can not delete. When I buy a hard drive, this is not to find me with a hard drive and a CD! So I put 1 star and it is expensive paid.
