June 29, 201511 yr Author Ok. I am getting there. One thing I wanted to see is if I could re-use the other "failing" drives. Is that possible, or are these drives worthless now? I did a preclear on one of them to see what the results would be: ========================================================================1.15 == WDCWD20EARS-00MVWB0 WD-WCAZA8054351 == Disk /dev/sdg has been successfully precleared == with a starting sector of 64 ============================================================================ ** Changed attributes in files: /tmp/smart_start_sdg /tmp/smart_finish_sdg ATTRIBUTE NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS RAW_VA LUE Seek_Error_Rate = 100 200 0 ok 0 Temperature_Celsius = 115 123 0 ok 35 Current_Pending_Sector = 1 200 0 near_thresh 65535 No SMART attributes are FAILING_NOW 12 sectors were pending re-allocation before the start of the preclear. 18 sectors were pending re-allocation after pre-read in cycle 1 of 1. 65535 sectors were pending re-allocation after zero of disk in cycle 1 of 1. 65535 sectors are pending re-allocation at the end of the preclear, a change of 65523 in the number of sectors pending re-allocation. 0 sectors had been re-allocated before the start of the preclear. 0 sectors are re-allocated at the end of the preclear, the number of sectors re-allocated did not change. root@Tower:/boot#

June 29, 201511 yr Since it looks too old for RMA try more pre-clears for science. Check the battery in your smoke detector...
