I just received this external hard drive. Nothing wrong with the delivery that was very correct even if the packaging for this type of device was a bit lighter. The connection to USB2 my PC and getting started posed no problem. The PC immediately recognized the drive without worry. I made a first backup my documents (400 go) with the free COBIAN and everything worked well and the backup was performed in just over 2 hours. Before, on my old external hard drive, an old STOREX, I put 4 times longer. So I put four stars because of course I can not for the moment found its reliability over time and a big negative is that there are no stupid ON / OFF switch. It remains on permanently when the PC is on and it's really unfortunate.
