I'm installing Windows 2003 SBS on a new machine at the moment. It has a Rocket Raid card in it with 4 channels, each of the channels has 160Gb SATA drives. I've installed the management software and have created the mirrored RAID 1 arrays no problem. But when I go to format the drives in the MMC, disk management I get disk failure across the board with all four drives. I then get asked to duplicate the arrays through the BIOS interface during boot up. When I try this, it starts off fine but fails at 85%. This is frustrating after a 3-hour wait. Any suggestions would be appreciated.
