Worst device I have ever owned! In the early days, everything was okay, and suddenly I should reformat the hard disk, as I have it connected to my PC (Windows 7). There was nothing left and on the disk were min. 50% of my data plan. Hard drive taken away to an acquaintance who works in IT. Nothing works, nothing left to save, hard drive formatting. After the first formatting the hard drive was about three times, and then again the same problem! I advise fully on the thing and going to buy as soon as possible a new one!
