Clicking drives can also sometimes be recovered wirh this method.

I think the clicking in that specific case comes from the fact that the drive sends the arm / heads to the parking position immediately when the rpm of the platter doesn’t match expectations, because rpm is critical for keeping the distance between head an platter.

Meaning the heads are ok, but clicking because a seized up bearing or motor doesn’t spin properly.

Be aware though, it is theoretically possible that ice crystals can form from air humidity condensating, which can cause the head to crash into the platter which makes the data definitely unrecoverable.
