I recently filled up my 3 TB MyBook Studio and was happy to know I could daisy-chain another MyBook Studio into the existing one. I was under the assumption (I know, never assume) that by daisy-chaining these two MyBook Studios together via Firewire 800, it would show up on my iMac as one large 6 TB drive. Instead, it shows up as two separate drives, each 3 TB.
Is this an incorrect assumption? Do I need to reformat both drives into a Raid configuration? What happens if I want to add another drive down the road but can’t back up my 6 TB of data before reconfiguring the Raid?
