    I assume that the external is formatted HFS+ and that you have tried repairing the permissions and the disk

    yah i've had that same message before when i tried to partition my external 320 hdd, i just totally erased my ext. hdd and restarted my computer and everything was fine,

    even though this problem has happened a few times with different drives i just erase and restart (sometimes a few times) and everything works fine (fingers crossed :D)

    Disk Utility doesn't re-partition on the fly. You will have to copy the existing data off, erase it, repartition it, and then copy the data back. Or pay for a 3rd party partitioner.

    <= 10.4.x could not.

    I'm not sure if 10.5.x allows for this. Let me check.

    There seems to be a lot of thought that you should be able to do this, but even more posts about how it doesn't work. I think it'll just be safer to do it the old fashioned way.
