Isn’t  the HDD hardware enscrited? How did you get it working in a no identical case?? I have a connection problem with mine, the led light, lights up but there is no usb connection nor is there any sound/ disk activity from the HDD 

if you dropped your drive and there is no sounds nor disk activity from HDD, then heads most likely jumped from parking onto the platters or didnt have enough time to reach parking if it was spinning when dropped; this is very common problem for laptop any drives, not just western digital. Heads on platters with no power kinda resembles the foot on brake pedal while car is in drive position… It wont move. If you put your ear to the drive while connected and it makes pulsing sound, like it attempts to spin - that’s the problem right there. Sticky heads

if drive makes no sounds then power delivery to the motor is breaking somewhere. Weather its your cable, or PCB on the drive itself.

To trouble shoot drive that doesnt spin:

  1. Put your ear to the drive and listen to it.

  2. Buzzing or pulsing - stuck heads

  3. No buzzing or pulsing - cable or PCB
