My WD Mybook 2TB is not detected only the light bleeps


I used my 2TB WD MyBook  the  first day perfectly but the second day only the liight bleeps at a constant ratio but is impossible to detect it as a external drive, so I tried in another lap and use another 3.0 cable and nothing happens, no sound, no reading, nothing! 

What can I do?

Replace the unit my friend, contact WD they will replace it for you.
