I thought /dev/ad4s2b meant the 5th disk (since its ad4; ad0-ad3 being 1st 
to 4th disks), 2nd slice (s2), and second partition in that slice (b). Do 
SATA drives too come up as "ad" devices? I don't have experience with SATA 
drives, so don't know ... I know my IDE drives come up as "ad" and so 
would assume SATA will come up with a different name.
