Gavin2812, You would likely need to move the drives to the other side of the backplane, in order to be visible to the controller. You shouldn't need to do anything beyond that I don't believe, but you may have a foreign configuration. If that is the case then import the foreign to proceed. Let me know how it goes.  
Quick question. I have a Dell Perc 6i RAID controller and need to move the port cable from A to B (cable length issues). Can I just move the connector over and keep the RAID? Or will I have to rebuild it as it is on a different port? Basically I connected it to port 1 (left side) and simply want to move it to port 0 (right side). Will it keep the Virtual Drive intact if I just move it? Thanks!
