This only works for specific mechanical failures, and I’d say about 25% of the time. It works because metal shrinks when cold, and this can sort of let a drive limp along for a short period of time to get small amounts of data off.

Drive clicking is the drive arm malfunctioning, and I wouldn’t expect the freezer trick to do much if it’s a messed up actuator or something. You already know the drive is bad though, so why not.

I used to take failed drives while they were powered on and kinda snap them really with a fast twisting motion in an attempt to get the arm to move or get the platters spinning.

It never worked.

  Yeah… That probably because either the drive thought it was falling and triggered the HDD falling mechanism (often found on 2.5" hdd) which would move the arms off the disks to prevent them from hitting it and damaging the platters to unrecoverable states.
  
  Or if done on 3.5" without this feature built into it, could just damage the platters.
  
  Would probably be less risky to open it up and unstick the arms yourself.

    It was on old 3.5" drives a long time ago, before anything fancy was ever built into the drives. It was in a seriously rough working environment anyway, so we saw a lot of failed drives. If strange experiments didn’t work to get the things working, mainly for lulz, the next option was to see if a sledge hammer would fix the problem. Funny thing… that never worked either.

    I’ve once had a hard drive of some particular vintage that wasn’t able to start. I did get it running with a hammer tap. Got the remains of data out and replaced the drive. It was nothing special, a Unix system drive with nothing that wasn’t on tape, but I just had to see if I could fix a hard drive with a hammer.
    
    I also remember one admin who would often be seen walking between computer maintenance room and workshop wing with drives and a blacksmiths hammer labelled “format”.

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.

Yup this was the first thing I tried. Nothing changed.
