Demystify the meaning of smartctl errors
by ddenial from LinuxQuestions.org on (#4VZ2Z)
Hello All,
My old harddisk has SMART enabled. Today, while going through man pages of smartctl tool, I came across the error option and tried that on my disk. Surprisingly it showed 5 errors. I'm not able to understand what they mean and when they happened.
Code:# smartctl -l error /dev/sda

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 5 occurred at disk power-on lifetime: 28352 hours (1181 days + 8 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
