The system is a Dell Poweredge R410, with two SATA disks in RAID 1.  It has been running for about three years.  Just over a month ago, disk 0 gradually failed.  And running diagnostics on it has confirmed it to be bad--at least initially, now it's dead and a PC won't even boot with it connected.

A replacement turned up as predicted to fail (by the system LED) once the RAID array was synchronized.  Pulling it and connecting it to a spare PC to run Seagate's diagnostics showed "SMART has been tripped" and the seller was willing to replace it as defective.

But the second replacement is showing evidence it is failing.  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?
