Disk Utility - Resize Partition

I'm using Snow Leopard on my Macbook Pro (i7, 2.7 GHz). I have a 500 GB HD that is divided into two partitions of 300 and 200 GB each.

I want to resize them in order to obtain two equal partition. Using Disk Utility, I was able to reduce the size of the top one (the one with the OS) but I cannot find a way to enlarge the bottom one to fill the blank space in between. In fact, I cannot drag the separator upwards, but only downwards (see the picture).

Any clue on how I might solve this without erasing all the data and create a band new partition? Thanks in advance.

MacBook Pro (13-inch Early 2011), Mac OS X (10.6.8)

This may be, but if the OP is looking to install different versions of OS X on the drive, then partitioning is essential.

The OP doesn't want to delete the bottom partition if possible (which it is not) except to expand the top partition and have unequal sized partitions.

Doesn't matter if he is or isn't installing another version of OS X. He wants to parttition for whatever reason. That is his choice.

Although your statement if fine for you for the OP it isn't.

There is - iPartition 3.4.1. But it costs $45.00. Or you can try to become an expert with Unix command line programming and risk losing everything unless you really know what you are doing. 🙂
