Since one drive originally had the OS on it, I was hoping that the raid card would mirror that bootable disk to the other disk sort of like dd will do if you do something like dd if=/dev/dev0 if=/dev/dev1 For all I know, it mirrored the blank disk to the bootable disk.:-( This is the first time I have ever set up a raid 1 controller so there are great knowledge gaps in my head. Thanks for your help. Martin McCormick
