I recommend to replace it ASAP. It is not worth further investigation - this drive has reached EOL. > smartctl -x /dev/sdf ... > Model Family: Western Digital RE4 > Device Model: WDC WD2003FYYS-02W0B0 > Serial Number: WD-WMAY00611922 ... > ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE > 1 Raw_Read_Error_Rate POSR-K 200 200 051 - 0 > 3 Spin_Up_Time POS--K 253 253 021 - 7350 > 4 Start_Stop_Count -O--CK 100 100 000 - 73 > 5 Reallocated_Sector_Ct PO--CK 200 200 140 - 0 > 7 Seek_Error_Rate -OSR-K 200 200 000 - 0 > 9 Power_On_Hours -O--CK 051 051 000 - 36231 > 10 Spin_Retry_Count -O--CK 100 253 000 - 0 > 11 Calibration_Retry_Count -O--CK 100 253 000 - 0 > 12 Power_Cycle_Count -O--CK 100 100 000 - 64 > 192 Power-Off_Retract_Count -O--CK 200 200 000 - 46 > 193 Load_Cycle_Count -O--CK 200 200 000 - 26 > 194 Temperature_Celsius -O---K 118 094 000 - 34 > 196 Reallocated_Event_Count -O--CK 200 200 000 - 0 > 197 Current_Pending_Sector -O--CK 200 200 000 - 0 > 198 Offline_Uncorrectable ----CK 200 200 000 - 0 > 199 UDMA_CRC_Error_Count -O--CK 200 200 000 - 0 > 200 Multi_Zone_Error_Rate ---R-- 200 200 000 - 2 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ... > 40 -- 51 0a 00 00 00 2a 25 4e 10 40 00 Error: UNC at LBA = > 0x2a254e10 = 707087888 ... > 40 -- 51 0a 00 00 00 1e 5a 3e 86 40 00 Error: UNC at LBA = > 0x1e5a3e86 = 509230726 ... > 40 -- 51 0a 00 00 00 1e 0c 77 d3 40 00 Error: UNC at LBA = > 0x1e0c77d3 = 504133587 ... > 40 -- 51 0a 00 00 00 1d e4 17 e7 40 00 Error: UNC at LBA = > 0x1de417e7 = 501487591 ... > 40 -- 51 0a 00 00 00 1d c0 73 99 40 00 Error: UNC at LBA = > 0x1dc07399 = 499151769 ... > 40 -- 51 0a 00 00 00 1d 23 fc 01 40 00 Error: UNC at LBA = > 0x1d23fc01 = 488897537 This disk also has stored a number of errors, but it does not look as bad as the first one. However, there are errors. I would replace it as well.
