I am fairly new to data-recovery so please bare with me

.
At present I am trying to get data off a friend's old HDD. It's a Western Digital WD200EB - 00BHF0.
The original drive does not spin up and unfortunately the lid has been removed and put back on again.
I bought a donor-drive and tried replacing the PCB. The drive spins up but clicks (approx. 2 times a second) and after a while spins down again.
My question is:
1. did removing of the lid damage the head-alignment or is this only an issue with new WD drives?
2. does the clicking come from not having replaced the controller-chip.
3. how can I continue or shall I give back the drive / dump it etc.?
Would be grateful for help!!!
Thanks a lot in advance!
