So I have this old Hitachi drive from 2008, its been in a pc from storage and is super slow. It is super quiet and doesn't have any audible noises besides the hum of the spinning. Though, its super slow. Booting time can take up to 2 minutes with nothing installed on the drive except OS. Opening a program can take up to a minute, and it is non-stop 100% disk usage, just stays and does not even drop 1%. Even after minutes of idle. Just curious as to what could be causing this?
