I have a Mac Pro with the following HD's 256 SSD - Boot Disk w/ Applications 128 SSD - Scratch Disk 2 x 2TB Black WD RAID 0 - Wife's Photography, User Data and Library 1 x 4TB Green WD - Music and iPhoto/Home movies My problem is that I have filled up the wife's photography RAID 0 drive and was hoping to transfer older pictures from Lightroom to an external drive, but I can't. When I try to move pictures I get weird permission errors. Then I found out it is impossible to fix permission errors on a RAID 0 drive on a mac. What should I do? My gameplan is to transfer everything from the 2 x 2tb RAID 0 to an external 4tb drive with Carbon Copy, and then wipe the old drives clean and start fresh. Is there another way? I also tried Drive Genius 3 with no luck. Disk Utility is worthless.
