Canceled partitioning process, hard drive space missing

[0makol16]

I was using Boot Camp Assistant to partition my MacBook to install XP. While partitioning my MacBook completely froze and wouldn't unfreeze, I waited about 30 minutes to see if it fix itself, so I held down the power to force a restart, upon rebooting I opened Boot Camp Assistant to try again and I noticed I lost 50 gigabytes of space. Is there a way to fix this and regain my lost hard drive space? Any help would be greatly appreciated.

NVM, I fixed it. I used the OS X install disk and repaired it, no idea why I didn't think of it before.
