the seek error rate could be linked to a failing power supply. The rest
should be just internal to the drive. Of course, also here a failing
power supply can be the cause.

Can you put the drives into another machine?

You must try to isolate the problem. It is a hardware problem on some
level. You must find out what it could be.

Or just run a single disk on plain UFS. And connect it to some other
plug. And disconnect all other drives.
