Up until recently, I had my MacBook Pro's hard drive in 3 partitions: 2 with Mac OS X, and one as a Bootcamp partition. I recently decided that I no longer needed to Mac OS X partitions, so after backing up all the files in one of the partitions I went into Disk Utility and deleted that partition, hoping I could expand the other one to take the free space. Unfortunately, now I have this area listed as "free space," and while I can make another partition in that space, I can't expand my existing partition to take advantage of it. Is there a way for me to get this space back, or perhaps merge 2 partitions together? I'm just afraid of losing ~400GB of space. Thanks for your help!
