Having some issues with disk 13 first being disabled and now being unassigned. Any thoughts, which harddisk is disk 13 and how I can reassigned it? I'll look into cabling once I know which disk I'd nee to look. Thanks!

Did you by chance write down the SN for your disk order? If not you will most likely have to pull disk by disk with the machine powered off. From your logs it found all these SN number so whatever SN number your cant find is the bad disk/cable
