I have a LaCie 4TB Quadra unit that was connected to my Mac. All the sudden I can no longer open it and it is unreadable. It's a 4 1TB drives in a RAID config (setting 0) to show as one large 4TB drive. The switch on the back makes the RAID config work properly.
If I troubleshoot this what happens if I switch the RAID button from settings 0 to settings 1,2,3,4,5,6,7? will it clear the drives? will it just show up differently on the computer until I reformat it, then its gone? Or will it change the configuration for the computer only temporarily, then change back without harm as long as I don't format it again? confusing, i know. hard to explain!
other than this, I loaded it onto a different machine and decided to do the general mac testing PAB-HD.tiff
