As has been mentioned several times, its own Phillips screwdriver must be used !!
I was also a little hard done when tightening the screws, as they were a bit small and often eindrehten side.
Installation:
Unscrew 2 screws at both ends. 3.5-inch hard drive to the Attach one end. Both slide together back into the housing and not push the short cable! This end with 2 screws tighten.
Before zuschraubt the back, you should definitely push the supplied plastic plates in the left and right side of the case where the guide rails / slots are available! This gives the hard disk sideways a very good grip.
After screwing the cable plug, and the device should be easily recognized by Windows.
Conclusion:
4.5 of 5
(Deduction for Schauben and screwdriver and a lack of installation instructions)
PS: If errors occur, I'll still resent.
