Hello,

I purchased my MacPro with (1) 500GB drive and recently purchased another 500GB drive. I would like to set up a RAID so that the drives essentially mirror each other automatically. Can someone please explain how to do this? I tried doing it via Disk Utility but it would only let me add the newest 500GB drive and not the 500GB drive that initially came with my MacPro. Thank you!

You can not include the MacOSX Boot drive/partition in a RAID array using Disc Utility.

Is there a reason that you cannot include the Mac OSX boot drive in the array? Because it would essentially try to make two boot drives?

Is there a possible way of getting around this? Basically, I want to store files on the one 500GB internal drive and have them mirrored to the second 500GB internal drive. Thank you.

Maybe just setup an automatic back up system...

Ok this is really weird, you know?

I was searching for something on RAID at Apple's Suppoet website and this came up in the hits: Disk Utility 10.5 Help.

They are talking about Leopard, right?

I don't think you can include your boot partition in a RAID array. If you boot from disk, you can create a RAID using your usual boot drive and your second drive.

Insert your Mac OS X disk and turn on the computer ...

Be sure not to overwrite your HDD though. That would suck. :ninja:

Yes, but the boot drive will split the RAID array. AFAIK, once you boot to a boot drive that is part of a RAID array it will no longer be a RAID array if you use Disc utility. I've tried this, that is what happened.
