I'd forgotten that some laptops, notably IBM models, had a motion sensor which, when triggered, would park the drive heads off the disc surface. This was meant to save the drive in the event of it dropping onto the ground. Perhaps not enough to protect from more sudden events.
Example: Lightning Storms, Laptops equal Mobile lightning rods.
Don't carry your laptop outside in stormy weather while using it at the same time.
Kind of a given but, yea.
