I've had my current Macbook Pro for a about a year and a half now. The first thing I did was swap out the HD for a larger one. I then partitioned the drive at around 75GB and 400GB. OSX is installed on the 75GB volume. My problem is that I've run out of room on the 75GB volume and there doesn't appear to be a way to combine the two partitions w/o losing data. Any suggestions? I'm wondering if I back up the data on the 400GB partition and then delete it if I'll be able to add more GB's to the initial 75GB partition. At a loss here so any help would be greatly appreciated. Thanks!
