I had RAID 1 configured on the operating system. Last week one of the drives died. Hence, no RAID. I have a new disk, but can't seem to get the Mirror option to re-appear. I downloaded the Navigator CD, but it doesn't boot when I restart, even though it has first boot priority, and the security on the hardware is disabled. I would like to load HP NetRaid Assistant from the CD, but seem to have something configured incorrectly. I think it must be in the Setup somewhere.
