Much of what is posted on the net about recovering from hardware related drive failures have been debunked as myths. In fact, you may actually ruin any chances of recovering data by doing so yourself.
I wouldn't advise trying to freeze the disk. This needs to be done in a controlled, sealed environment for specific types of hardware failures. See Seagate article
Friends don’t let friends freeze their hard drives!Another factor in modern hard drives is that the drive's PCB board may contain flashed HD calibration data, specific to that drive when assembled. So replacing the PCB with an identical model does not work in most cases.
