AmesMUG: Resizing HFS+ partitions

[John Rearick]

I haven't done this myself, but I would assume that you can't do this  
on a live filesystem.  Also, I would make sure you have rights to the  
volume (perhaps run as sudo?).  I am also assuming you have free,  
unpartitioned space on the drive next to the partition you are trying  
enlarge.  This is about as far as I can go on this subject.  Perhaps  
a Google for "nondestructive partition resize diskutil" might be a  
place to start?  http://www.ffnn.nl/pages/articles/apple-mac-os-x/ 
nondestructive-partitioning.php also seems to be a good step-by-step  
guide that may be helpful getting to working with your filesystem in  
a non-live state.
