December 1, 2025Dec 1 Yesterday, I added a new Parity drive to my array, and it has been working on building parity on the new drive.Today, I see that one of the drives in the array has an "X" and the tip pops up as "Device is Disabled - click to spin up"I click it and see Disk 3 settings. There is nothing like "spin up" visible.On the Attributes tab I see this:Self-test tab looks like this. Still nothing about how to spin up.Edit: Here is the log for the drive:Edit2: If Disk 3 is dead, should I wait until the Parity 1 drive rebuild has completed before replacing, and thus starting a rebuild of Disk 3?
