Is it possible to repartition a hard drive without having to erase it.<br><br>I have a firewire drive I use for a back up. I'd like to repartition it so I can put another version of OS X on it. I have 10.3.9 on the firewire drive now and it's formatted as one big partition. I'd like to make that partition smaller so I can put a second partition on it and install 10.2.8<br><br><br><br>
