Thanks Michael,

 I have already been through the SCSI Select/HostRAID ROM and configured 
the disks as RAID0.

 I am unfortunately at work at this moment, so I can not check ar0, 
however I seem to recall it is already taken by my ATA array. I had not 
mentioned this array as it is only for storage and the problem exists 
regardless of whether or not it is connected.

Regards
