Hello,
I thought I would repurpose my old tower into a NAS. I purchased 2 x 6TB WD Red's but one disk is always shown as disabled. I tried switching SATA connectors with no luck. Running SMART self test as I write this post, but I don't think the problem is with the HDD. The motherboard is an Asus Maximus V Gene V - Z77 chipset. Could this be due to a capacity limitation?
