Answer:The second 8-pin chip is a FETky. There is no need to swap it.
I would say that your drive may have a preamp failure. This chip is on the headstack. That’s a common consequence of an overvoltage on the +5V input.
You can use a USB-serial TTL adapter (US$5) to view the drive’s error report via terminal. That should tell us more about the fault.
