Hi, I'm hoping someone can help. I'm trying to set up my new 920+. It's just been delivered so I installed the 4 brand new ironwolf pro 6tb drive's and fired it up. When it comes to creating a pool only 2 of the drives are showing. I've powered it down and swapped the drives around and the same 2 drive's are not being detected. I want to create a Raid 5 array so really hoping they aren't dead-on-arrival. Can anyone suggest anything I might have done wrong? Thanks
