Here it was 50:50 failure on the Seagate disks - some older disks/models
failed after 5-6y some kept running for 10+ andwere decommissioned. I did
some research may be 7y ago and started buying 2TB WD RED for NAS - was
recommended for RAID. They seem to be good.

I think Kate means to move the magnetic disks from the failed driver to the
one that you know is working. Clearly you can not use different make/model.
But it is risky task.
