Did you know the contacts to the head, preamp and the motor on regular spinning disks are not soldered nowadays? That's right, after some clever PLM engineering, companies decided NOT to do this. Why? It shortens the life span of the disk, thus, your disks die and you go and buy new ones.
Mitigation of this problem: Remove the controller board from the drive and solder (add solder) to all of the contacts that connect to something to the aluminium chassis of the disk.
DON'T DO THIS, at best it'll do nothing and at worst (muuch more likely) you'll short and kill your HDD.
The whole point of contacts is that they aren't soldered, the transmit current by physical contact. There's a matching pair on the HDD chassis:
They're not soldered, as in soldered to pins on the aluminium chassis. Look at the image I posted, have I soldered anything from that board to the aluminium chassis? No. The're solder cushions to act as pillows for the metal head/preamp pins, which leads to having wider contact surface and no oxidation, which in turn leads to better conductivity, no head fly-bys and no head crashes when the head looses contact with the control board.
BTW, they used to make them with solder cushions, but stopped after a while, cuz those disks could go through hell and back. Remove the boards from some old early 2000's drives, you'll see what I'm talking about.
Gold does not oxidize in atmosphere. You are spouting nonsense you do not understand.
