Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 8 occurred at disk power-on lifetime: 34865 hours (1452 days + 17 hours)

答案1
Power_On_Hours在 smartctl 中为 2324，在 CrystalDiskInfo 中为 2325。在我看来还不错。
