All i can say is that from my personal experience it has worked, And for others as well.

What you can do is: Get a drive that is exactly the same model, size etc. It has to have been manufactured around the same time. Plug the new (working drive) into your Pc (keep both drives out of the case upside down so the logic boards are accessible) once the drive has mounted in windows, you need to put the drive to sleep (you can set windows to put hdd's to sleep after 5min) then while the HDD is asleep, with a T8 screwdriver carefully remove the board without shorting any components & leave the Power & SATA cable plugged in. Then screw it onto the bad HDD (with faulty board removed obviously) Then browse the disk & you should be able to see\backup the data. DO AT YOUR OWN RISK obviously.
