    Are you booting off the hard disk you're trying to alter? You cannot boot up off your main hard drive and then try to repartition it.

    Secondly do you have a backup of your data/system? Doing any partition work, really means you should have a backup. Mostly because the task of repartitioning a drive can be destructive, i.e., the partitions get formatted.

    Reboot and run disk utility and see if those errors continue. A partition process may have started and failed to finish correctly, or may just be that you tried to alter the drive while it was locked.
