I have been told that the failed logic board of my hdd - model ST3200822A - is the reason that I can't retrieve many old photos stored on it. How do I find out if the board is still available? Is there a way to test if the problem is definitely only the board, and mitigate the risk of purchasing a new board only to find out that the data is still not recoverable?

To set up a diagnosis, we should first know the symptoms.

Maybe the motor is stuck. Who knows, you must definitely carefuly diagnose your drive.

Does the drive spin up?

If not, then upload a detailed photo of the component side of the PCB.
