    So I have a MAC BOOK PRO, running Lion.

    Here is the situation; I attempted to split the single main partition by creating a newer smaller one which was initially planned to support 20GB.

    I accidentally split the main partition in half; and ignorantly tried to prevent the completion of said task by interrupting the process.

    It is only after I had forcefully closed the Disk Utility app, that I had realized that my partition displayed itself as officially full. I am now unable to split partitions.

    The dark shaded space isn't what Disk Utility sees as full. It's how small you can make the partition. Have you tried verifying the disk?

    I did as you instructed, and here is the result.


    Should I proceed as it commands? Will I loose data?

    To repair the disk you need to run Disk Utility from the Recovery partition.

    To find out, where you hard drive capacity is being used, you can use the following free applications:
    Maybe try a combination of several, if you still can't find the "missing" capacity.

    Make sure you have a good backup. You do have one from before you started, i'm sure, right?

    Thanks for the support, I just fixed the issue by booting into Disk Utility and performing a Repair Disk.

    Thanks again.
