And it doesn't detect it when I do it manually. Also the bios chip presents additional issues. I believe when I don't have a raid array set up, it won't boot at all. When I have it on raid10, I had trouble booting, and when I have it on concatenation, everything works fine, until a drive is replaced. At that point, i have to recreate the array, as concatenation is not a fault tolerant set, and at this point I seem to lose all my data. Is there a way to get it to use the raid that's part of the bios chip? Something about device mapper? Russ
