Listen to whether it has been non-stop, there is a regular sound (because the disk is a circle is the head will be circular to read it) if the hard drive normal read the sound is intermittent sometimes not
If the slight bad way may sound small can not hear to be able to use the hand to grind the hard disk to feel like also may
Hard drive fever is normal but bad track hard drive is hotter than usual
And in the hard drive read the bad road when the machine will express slow down or card a bit sometimes still crash
