I have a G5 Dual 2.3 GHz with 2 GB RAM and two 250GB HD's. Currently I have the software RAID set up in Tigger so that I have 2 copies of all my files (1 on each HD). I am wondering if anyone has upgraded to Leopard that is also using the software RAID. I will be doing the upgrade install. Will I need to set up the RAID again after installing Leopard or will Leopard "realize" from the current configuration that the 2 HD's should be set up as a RAID? Cheers.
