I got a new 500gb seagate to go in the MacPro, but I do not want to reinstall everything. Is there a way I can clone my current hard drive. I have an external that I have been using for time machine. I would like everything to be the exactly same as my current configuration. Is there a way to do this so that I can move the 500gb as my main drive and put the 320gb as my secondary while transferring all my data to the new hard drive and erasing the old drive. Thanks
