Hrm....it looks like asking for page 0x80 directly is returning the same
as requesting page 0x80 or asking for all pages:

sudo camcontrol devlist
<SEAGATE ST373207LC D701>          at scbus0 target 0 lun 0 (da0,pass0)
<SEAGATE ST373207LC 0003>          at scbus0 target 1 lun 0 (da1,pass1)
<PE/PV 1x2 SCSI BP 1.0>            at scbus0 target 6 lun 0 (ses0,pass2)
<Rorke GalaxyHD 342D>              at scbus1 target 1 lun 0 (da2,pass3)
<TOSHIBA TransMemory 5.00>         at scbus2 target 0 lun 0 (pass4,da3)

sudo camcontrol cmd pass4 -v -c "12 01 00 00 255 00" -i 255 "-" | hd
