Hello! I heard that sometimes hard drive can get damaged (holding down the power button to force shut down, for example when system is completely frozen - it has happened once or twice for me, no idea why). If hard drive is damaged, would it weaken security in some way? Like OS doesn't function properly and something develops security hole or won't notice something malicious - like Gatekeeper letting something through or security patches not working ? How would I know if hard drive is damaged? Sorry for likely dumb question, but I'm trying to figure it out with absolutely no idea about tech.
