i Have Seagate 1 Tb Hdd

Model : ST3100322CS
P/N : 9Gw134-075
Firmware : ca13

First i found PCB Problem. And Replaced Pcb with Same model with Same Firmware .
Now Hearing Hdd Clicking Sound,, And Spin Downing Ofter few Clicks.. How To Fine Where The problem it is..
if firmware Fails (i Have Doubt about Firmware might not working properly).. Hdd Will Click?????
or another Problem??

how you determine that pcb is faulty at first place ?
a straight pcb swap will not work on these Seagate drives.
better seek professional assistance if data is important.

Original PCB don't have any damages but when connected with original PCB HDD not spinning . that indicates might be PCB faulty.. So I swap PCB. I need answer about if bios chip is mis-mach drive will click ???

post original PCB and donor PCB

Why you people not answering exact what i am asking .
Can any one please say if Bios chip (firmware chip) burnt or mismaches HDD will click or not ??

My educated guess is because it is not easy to understand what the problem is based on the description you provided and how your questions fit in the case described.

Generally speaking, non-compatible firmware on a PCB with firmware on the drive in Seagates will result in clicks and spin down. But there are exceptions as the compatibility factors are of various levels.

Drive would most likely click if the FW chip is not original
