Hey all, I've not done RAID mirroring before and I ran into some trouble in Disk Utility. Here is what I want: Disk 1: Main drive (1TB) Disk 2: Mirror of Main drive (1TB) Disk 3: Time Machine (1TB) Some posts from the interblogz say that you cannot Mirror the startup disk. That doesn't seem to make much sense, but I'll believe it if it's true! When I tried to set up the Mirror in Disk Utility, I couldn't get the two disks to drag into a mirrored set. Any thoughts?
