In order for the new controler to work it needs to be setup. When new it has no config. You'd need to create a logical drive stripe size, array size etc from the new controller bios point of view. Make sure these settings are exactly the same setup as the old controller is using. Usually creating a logical drive (RAID X) Is a destructive process. I could be wrong. Get a good backup first before changing controllers, then try it, and you'll have Nothing but time to loose.home | help
