SMART Error Log Version: 1
ATA Error Count: 23288 (device log contains only the most recent five errors)
CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]

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 23288 occurred at disk power-on lifetime: 6540 hours (272 days + 12 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
