I had just one 4T drive in mt EX4. I bought a second but couldn’t find clear instructuions about adding aditional drives. So to be save, I shut it down, added the drive and booted it back up. The LCD screen reads ‘Disk inserted into Bay 2’ But i’ve not been prompted to format it or anything. And I dont see it in the interface. My intention is to backup Bay 1 onto Bay 2. Both drives are WD Red 4TB NAS Hard Drives. How do I format the drive in Bay 2 and set it up to backup Bay 1?
Additionally, the blue light above Bay one is flashing. I am not reading from or writeing to the drive. Why is it doing that?
