Does the box you are trying this on have a SECURELEVEL set?

kern_securelevel="3"  (or 2 or other number)

After one of the secure levels, you cannot open disks for writing.   
You will have to reset it to NO and reboot and do what you need.   
Read in the handbook for exact details, which I cannot remember now  
(like at which secure level this takes effect)
