Also, sdc has a much lower event count than the other drives, is that normal? /dev/sdc is the first drive that failed /dev/sdb is the one that was kicked after
Can you please post dmesg output from when you unplugged the drive and what happened to the array then? I guess you do not have "cat /proc/mdstat" from then? It's weird that sdb was busy. Please post mdadm version and kernel version.
The event count is increased when writes occur to the array, so that sdc would have a much lower event count is normal because it was out of the array for much longer time than sdb was.
