Hi
I recently bought a 3tb wd green hd, which I dropped to the floor, and since then not work.
I opened the hdd and the platters are ok, nothing seems damaged but when I turn it on, the platters starts rotating and the head tries to read the platters but returns to its original position without doing anything. After a few seconds the platters stops to rotate.
Maybe the head is damaged?. Where can I buy a head replacement?.
I'm pretty novice in hard disk repairing world but i think this is the perfect chance to start learning

Thanks in advance.
Greetings.
