So now trying to figure how the SATA interface can work to the extent it properly reads and writes the drive, but causes it to go bad.  Or else I've gotten two defective hard drives.  Has anyone seen a situation where a disk has been broken by a system that is able to successfully access it?

I've never come across anything like this either.  I also don't
understand how one of two disks in a RAID1 array failing would cause a
system to stop booting.  Sounds to me like you've got far bigger
problems than just a bad disk.
