If the hard drive works at cold temperature, it looks like the circuit
board
has cold solder joints. I will try to re-solder all solder joints on the
circuit before put it into fridge.



That's not what the freezer does, getting the drive cold affects the
properties of the IC's themselves as well as it can change the physical
alignment of the mechanical portion of the drive slightly. I've had some
luck with the freezer trick but I've never found cold solder joints on a
drive.
