November 24, 20178 yr Did you set any more specific SMART settings for this disk, if so clear them? (see Main -> <disk name> -> SMART settings)
November 24, 20178 yr Author No, they are at their default values: I'll try changing one to something else and toggling it back.
November 24, 20178 yr Author Yes, that fixed it. I changed the first option to "Raw", saved it, then changed it back to "Use default" and saved again. Thank you for the pointer, @bonienl
