Hi,
Long story short this drive died 6-7years ago, I am thinking about trying PCB replacement or check and compare the PCB components via multimeter one by one.

I would really appreciate is someone have this identical drive with identical PCB.

Seagate Barracuda 7200.12 250Gb HDD
PCB number: 100535704 REV C

*** It might be possible that some other Seagate HDD have this exact PCB ( PCB number: 100535704 REV C ), so if the drive is different model number but the PCB is same than I might take that drive too ***

Easiest way to know the PCB number is just flip the HDD to PCB side and locate the number on right hand side of PCB, you don't even need to remove the PCB to find the number it's just on top. (see the image below)

Even of you find a compatible pcb you will have to manually switch the eeprom chip from the faulty board to the new one . A direct swap will not work as the eeprom stores all the hdd heads telemetry .

Yes I know about that and I can replace that chip.
First I will try to match the component value one by one (via multimeter) on both boards to see if something on my board died and if I couldn't find something dead then I will just swap the eeprom chip from my board to good board.

Also mention how to find pcb no on windows

I don't really know if it's possible to know pcb number from windows.

Bought a same pcb drive locally,
@ankushv replaced the eeprom chip on good known board and tried to boot the drive but unfortunately the issue remained the same which concludes that my old pcb is fine and the fault is in the header or platter or motor of the drive.

The issue with drive is that it spins but does not get detected on boot, PC hangs for a couple mins on boot trying to detect it but then boots in os without recognising it(os is installed on SSD)

In disk management it shows something like this
