When I first got my 17" 500 Gig MBP, I partitioned it into two hard drives. A mistake I now regret. And now my start-up hard drive, which includes all my valuable software, is down to only 280 MB left, which will not allow me to do simple number cruching in my applications. Is there ANY way I can departition my hard drive, so I will be able to have one big hard drive, without losing all my applications. I don't think I can back up my Photoshop, Illustrator, Flash, and others, to a back up hard drive, and then transfer them back after departitioning, and actually have them all work. Any ideas!?
