Installing a hard drive in the Viper U3 is very easy. To begin, remove the two screws on the back of the enclosure and slide out the rear panel and inner tray.
The next step is to mount the hard drive to the tray. The easiest way to do this to place the hard drive on top of the tray and line it up with the SATA connectors on the backplane. Gently push the hard drive onto the connectors and then flip the tray over and screw it into place. I recommend using the screws that come with the Viper U3 as they are low profile and will not cause the tray to hang up on the enclosure.
With the hard drives installed, insert the tray into the enclosure and screw the rear panel into place. Once this is done, you can go ahead and connect the USB 3.0 cable, plug in the power cable, and turn the enclosure on. If everything goes as planned, your computer should automatically detect the Viper U3 and install any drivers it may need.
