Terry,
For some years now IT professionals have been warning about the folly of rebuilding small RAID arrays built with multi-terabyte SATA drives as this is very likely to corrupt the array & lose all its data with no recourse. Current best practice is to never try to rebuild, but to simply copy the data off to another backup array, then to replace the failed drive, format the array and start from scratch. Lots of articles online about this problem, e.g.:
