  If I try that with the ad6 disk removed I get the following error:

    atacontrol: ioctl(ATARAIDADDSPARE): Device not configured

  If I insert the disk I had removed (but this time I formated it
  through the BIOS) it panics with the following message:

    ar0: 152627MB <ATA RAID1 array> [19457/255/63] status: READY

  I'm worried about how am I going to replace a dead disk if it won't 
let me boot with a new disk inserted as ad6.

Thanks,
