    I was partitioning my main hard drive when the computer quit, had to restart and now main hard drive shows only 546 GB of the 750 GB available. But does not show a second partition. If I go to partition the hard drive and click on the plus sign, 206 GB show up. I have tried deleting the 206 but to no avail, how do I get the main drive back to 750 GB?

    Also if I try and shrink the partition to 100 GB, I wind up getting this message:

    Partition failed with the error:

    Couldn’t modify partition map because file system verification failed.. Besides doing a full format how can I get the main drive back to 750 GB?

    I don't think you can except by reformatting and starting again.

    Yeah, if that 546Gb Partition is your OS X partition, cloning or backing up the drive and starting again would most likely be the only option?

    Are you at all able to create a new partition from that "free space".

    That's it, I'm afraid, I don't believe you have any other option.

    Try doing a command-r boot to recovery and use Disk Util to run repair disk, then see if you can manipulate the partitions while still in recovery.
