Complete error log: SMART Error Log Version: 1 ATA Error Count: 1564 (device log contains only the most recent five errors) CR = Command Register [HEX] FR = Features Register [HEX] SC = Sector Count Register [HEX] SN = Sector Number Register [HEX] CL = Cylinder Low Register [HEX] CH = Cylinder High Register [HEX] DH = Device/Head Register [HEX] DC = Device Command Register [HEX] ER = Error register [HEX] ST = Status 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 1564 occurred at disk power-on lifetime: 445 hours (18 days + 13 hours) When the command that caused the error occurred, the device was active or idle. After command completion occurred, registers were: ER ST SC SN CL CH DH -- -- -- -- -- -- -- 40 51 00 71 09 24 00 Error: UNC at LBA = 0x00240971 = 2361713 Commands leading to the command that caused the error were: CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name -- -- -- -- -- -- -- -- ---------------- -------------------- 25 00 01 71 09 24 e0 00 00:01:23.506 READ DMA EXT 29 00 01 ff ff ff ef 00 00:01:23.493 READ MULTIPLE EXT ef 02 01 01 00 00 e0 00 00:01:23.261 SET FEATURES [Enable write cache] ef aa 01 01 00 00 e0 00 00:01:23.261 SET FEATURES [Enable read look-ahead] 25 00 01 8f 09 24 e0 00 00:01:23.253 READ DMA EXT Error 1563 occurred at disk power-on lifetime: 445 hours (18 days + 13 hours) When the command that caused the error occurred, the device was active or idle.
