Hi! I have a 1TB disk. It is now almost full. I just got a new 1TB disk and I want to make a mirrored RAID set of the two. If I create a RAID set in Disk Utility, does that erase my first disk? Or does it just mirror everything to the second?
 
Ok, thanks. Good to know. I guess it's just assumed common knowledge, because that doesn't show up in the Apple documentation.
