December 28, 20223 yr So my server threw this code at me the other day, Last SMART test result: Completed: read failure. along with this smart error log ATA Error Count: 1 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 1 occurred at disk power-on lifetime: 1238 hours (51 days + 14 hours) When the command that caused the error occurred, the device was active or idle.

Any advice? Does Unraid account for this?
