If you have something compatible and JBODish available, you can also
plonk the suspect disk in that and ask it how it's feeling with
smartmontools before taking a decision on reinserting it. Doing a
RAID5 rebuild and risking provoking one of the remaining disks to
throw a fit in the process only to discover that the rejected drive
really was in its death throes would be really, really tiresome.
