So today I added another Ironwolf 10TB to my system and started pre-clearing/stress testing before I allocate it as a 2nd parity drive. I powered down to add the drive to a bay on my enclosure. As I wanted both parity drives on the motherboard SATA controllers, I had to move my recently rebuilt 8TB  (Disk 8; rebuilt successfully earlier last week) to another bay.    Upon rebooting, the recently rebuilt 8TB (Disk #8) threw a bunch of read errors. I suspected the bay might be at fault so
