Are you _sure_ that the array is being recognized properly?

Based on the dmesg output, it looks like the controller is being read
as a 74G drive.

FWIW, this is the section of my dmesg output, for a _mirror_:

   ad4: 78167MB <Maxtor 6Y080P0 YAR41BW0> at ata2-master UDMA133
   ad6: 78167MB <Maxtor 6Y080P0 YAR41BW0> at ata3-master UDMA133
   ar0: 77247MB <Promise Fasttrak RAID1> status: READY
   ar0: disk0 READY (master) using ad4 at ata2-master
   ar0: disk1 READY (mirror) using ad6 at ata3-master
