[QUOTE="Sur3Mac, post: 912766, member: 113359"] If you're talking about making a raid mirror without formatting, It's even pretty easy to do. Make sure you have a good backup. We are going to be re-writing the partition map of your disk. If something were to go wrong you could loose all of your data. That said, this seems to be pretty reliable. If you want to mirror your boot device you will need to startup off of something else first. Next open the Terminal and type [b]diskutil list[/b] You'll get an output that looks something like this, The main thing we are looking for here is the device name of our disks. Let's pretend we are going to make a mirror of our boot disk, disk0. We've decided that we want to create a mirror of disk0 so type [b]diskutil enableRAID mirror disk0[/b] and the drive in question will vanish from the desktop, but it will reappear in like 20 sec. Now that your drive is back you can rebuild the new RAID set with either with a diskutil repairMirror (RAID device name) (Bad slice) (Good member) (New member) or just open up Disk Utility, drag and drop, and then watch the pretty progress bar. If you mirrored your boot device you can startup off of it and get back to work before you rebuild since you can rebuild in the background now. Note: Mirroring can take a pretty long time... like an hour for 10 GB's! Hope this is what you're looking for.;D [/QUOTE]
