Raw value, which I assume is what matters, is 0:

    ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE     
    UPDATED  WHEN_FAILED RAW_VALUE
      1 Raw_Read_Error_Rate     0x000b   100   100   050    Pre-fail

      2 Throughput_Performance  0x0005   100   100   050    Pre-fail

Current_Pending_Sector is 1, which I read on Google implies there is a
bad sector.

Does

    # hdparm -D1 /dev/hda

    /dev/hda:
     setting drive defect management to 1
     HDIO_DRIVE_CMD(defectmgmt) failed: Input/output error

mean anything?
