What are some examples or situations in which a laptop's hard drive can be damaged? Because I usually put my laptop on top of a table when I'm using it. The table is not fixed to the floor and sometimes when I accidentally hit it why my leg(s) it shakes causing a vibration which also shakes the laptop for a bit. Can that, for example, cause damage to my laptop's hard drive? Also, can you cite some tips on how to avoid hard disk damage? Any answer would be greatly appreciated. Thank you.
