I have a HP Microserver running FreeNAS 9.10.2, with one 4Tb hard drive that I use to store media to stream over my home network. I've put in a new 4Tb hard drive as I was running out of space, but can't for the life of me see how to get it setup. I want it as a seperate hard drive for storage which is totally independent of the first drive, and don't want data spread across both of them. Any idea how I do this please?
