SMART Check Warning - Reallocated Sectors Count = Fail

On El Capitan, Bay3/4 were a RAID.1 (3.33 12-core Mac Pro). Bay3 broke (click, click) - a frequent result of El Capitan's induced RAID issues I hear.

Replaced Bay3/4 with new RAID.0 and relocated remaining/working RAID.1 from Bay4 to Bay2.

Upgraded OS to High Sierra, reconfigured (old Bay4) new Bay2 to a 3/partition Carbon Copy Cloner backUp from RAID.0 - the new 3/partitioned RAID.0 group in Bay3/4.

Tech Tool 9.5.3 insists Reallocation Sectors Count on newly configured CCC backUp Bay2 drive is a FAIL. Disk Doctor can find no issue with each of CCC's 3/partitions or main drive unit.

Is it possible there's a TechTool cache file somewhere that has this drives "former config" still logged?

Thanks
