I bought this to replace a HDD Toshiba another who had a small technical problem (nothing serious but I'm backing up data with, I prefer the safe side with a new disk). His appearance is quite correct. It seems robust. There are small rubber pads that will not slip once on the desk (it is a great idea). Otherwise, no bp recognition on my PC (tested on 2 PC, Win 7 USB2 and USB3 Win 8 and no worries) Transfer times are nickel. Very good product for me.
