Yes I am adding a new slot, and I don't expect it to have data on it, after I tried to add the drive as a new slot Unraid ran it's own check on it, and said Unmountable: not mounted, so I removed it back to unassigned devices and ran preclear and then re added it as a slot and then unraid said rebuilding drive and still came up as Unmountable: not mounted, what part of the diagnostics would you like me to post
