Simple. If the surface is decaying, it will be localised. It's decided to hit the locality of the uefi partition. This is what would, in the old days, lead to a head crash. Once the magnetic layer started to physically deform (flake), the head would hit it which would start a cascade of debris scouring the disk surface and trashing the heads. Cheers, Wol
