No, I created a partition on it with windows disk management. I suppose I could try deleting and formatting a new partition, with windows setup this time. But windows setup did copy files on it, so the drive is recognized... Ok, so this error message is probably not related to the SATA/RAID stuff. I'm still confused though... do people only need to integrate the raid drivers if they have RAID fuction enabled, or is driver integration necessary for any SATA drive connected to a nForce motherboard, when installing windows nlite (unattended) ?
