And, can you tell me why HDD does not last long even though it was never dropped, hit, etc.. It's just there, without being interrupted. My Samsung HDD 750GB Sata only lasted for a year. But suddenly, it just starting to not function properly. S.M.A.R.T shows the Spin Up Time failed (red), over 2000 bad sectors found and 74 delays detected (I used HDD Regenerator). What cause HDD failed suddenly? Is it because of PSU (over voltages), RAM, processor, cables, or electricity prob (suddenly shutdown), or any?
