1TB HDD stopped working all of the sudden. Spins up fine with no audible clicking or grinding. 9 times out of 10 it is not recognized by OS or BIOS, and when it is. it's inaccessible. From my research, I'm guessing it's a faulty PCB.
Sounds like your Paddle-card is dead. Drive works fine but data isn't going from platter to platter.
Not really something I'd recommend the average User operate on, but you can find a dead drive and switch them out. You literally pull the one off the dead drive and swap it out with your good one.
Hope this helps.

cannot second this enough. MIGHT fix it if you know what you're doing.
I'd use one of the 1/10th times you have with it working to BACK UP EVERYTHING YOU GIVE A SHIT ABOUT as any attempted opening / fixing of the HDD has a high chance of fucking it over for good.
