Great thank you for the advice!

Yes, I must have unassigned the disk and reassigned it to try and fix the unmountable status as well. Yes, the rebuild was on top of the old disk, the working data drive that became unmountable. If filesystem is severely corrupted, then is data recovery possible or should a clean wipe and format be done and take the loss of data? Thank you.

This is what appears running without -n:

Thank you! Will do.

Did not stop array before pulling an unmounted drive from array. Pulled another array mounted disk drive by mistake, said disk drive became unmountable after popping the disk drive back in. Rebooted unraid for a clean shutdown hoping it would fix the connection. Data rebuild automatically starts when array starts. I let the rebuild finish. Drive still unmountable, contents emulated. Sign next to drive is orange triangle with exclamation; hovering over it states "Device Contents Emulated Click to Spin Down Device". Tried to google issue. Seems that there should not have been a reboot and the unmountable drive should have been subjected to xfs_repair before rebuild. Need to figure out whether time should be trying another rebuild, trying a software recovery of the files, or just clearing the disk and taking the loss. Thank you for your assistance. Diagnostics and SMART data of unmountable drive are attached. tower-diagnostics-20241230-1815.zip tower-smart-20241230-1817.zip
