When I got this case I was rather satisfied with my purchase. Indeed it is very easy to put a hard drive inside and replace with another. As for the installation is simple! But now after only 3 uses the case is no longer recognized by my computer. I'm repeatedly reconnect the USB port, no sound and message indicating the connection of a new device. I tried everything to make it work like changing USB cable or start in Safe mode. Nothing! Nada! Finito! the housing serves me for nothing! Luckily I had bought a DIGITUS adapter have new access to my hard drive. In short, my tip of the day: Do not buy this product!
