I just bought a DS213 with 2 x 2tb but not sure how to set it up. I want to set it up as 1 hdd with 2 partitions. Each partitions will be used as TM for 2 MBP. The other hdd will be for NAS stuff and an external 1 TB for files back up. Can someone point me to the right direction? Do i have to format it to Journal? If yes then how do i do it?
