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 once had a hard drive of some particular vintage that wasn't able to start. I did actually 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".
