I have a 4yr old seagate+2yr old samsung which are running quite fine however since i changed the position of my pc to a less ventilated space i dloaded speedfan to check if they were gettin too hot.The temps were ok averaging at 30c but i was surprised to find that it waz showing my seagate to be at 50%fitness while the sam at 90%fitness.What i want to know is should i get worried?Is my HDD going to die?What reliable method should i use to check my HDD health?Are my HDD's too old?Should i get a new one?
