If it knocks on powering then it means it cannot read from Servo information. In such case there is some malfunction preventing heads to read, probably heads are bad.

After reach DRDY with 0 capacity, check if spindle is powered or if it stops. I have a feeling it stops and probably you have some mechanical problems internally.
