This is an Intel 875P motherboard, and I think the controller only supports striping, not mirroring. If this is not the case, I'd happily try it, although it would take a while for me to find the time to back up and migrate my data if there are any incompatibilities. Nevertheless, this completely skirts the issue that there are races in the ata driver that are exacerbated by using ccd(4). ATA RAID would only be a workaround.Received on Wed May 05 2004 - 11:09:15 UTC
