(You would have to back up, partition (which wipes your data), and then restore your data.) But there are several third party utilties that claim to reliably allow you to partition without having to erase your drive. iPartition http://www.coriolis-systems.com/iPartition.php Drive Genius http://www.prosoftengineering.com/products/drive_genius_info.php DiskStudio http://micromat.com/diskstudio/ds_introduction.html StorDirector http://www.commandsoft.com/product_stordir.jsp VolumeWorks http://www.subrosasoft.com/thestore/product_info.php?products_id=431 Personally I would be too afraid to use any of these utilities without having a complete backup of all of my data first.
