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 2 occurred at disk power-on lifetime: 6383 hours (265 days + 23 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
