Thanks! Diagnostics attached. If the array starts what might you look for in the diagnostics? If all good I presumably format the disk and then add it to the array? tower-diagnostics-20231002-1924.zip

I have 3 14tb drives used to create an array. There was a power outage recently and now upon booting I see one disk is marked "Unmountable: Unsupported partition layout". Regarding the array health: Since this disk was originally part of the array shouldn't I expect to see an error somewhere? All of my data appears to still be available - since this drive was added the the array last is it possible it's unused? Parity check ran without issue (09-28-2023). Regarding the disk itself: Ran SMART short test which returned no errors (will update once extended test completes). Any suggestions for how to diagnose what has happened to it?
