1tb mybook not recognized by computer, only lock lights up

ok this just happened today suddenly. it was working hours ago. suddenly my macbook doesnt recognize it and it looks like only the lock shaped light on it is lit up. the bar shaped light is not lighting up. it still has power to it and sounds like it is working, but my computer is not recognizing it.

Is the drive password protected?


Or is the drive asking for a password?

same problem here. help me wd god!!!
