Hi, I have a Lacie Big Disk Extreme + which has two 500GB drives inside raided together to make 1TB. However, the drives got took out to be used inside a Mac Pro for a while. Does anyone know if they can be raided back together? I tried once using disk utility and thought I had done it but it after that the drive went in to storage for a while. Tried it today and the computer will not see it. I have no reason to think the disks are in any way damaged.
