Recovering a lost file system off a hard drive?

I was repartioning my hard drive, and I was in the process of moving a partition left and resizing it, when I accidentally hit the "Cancel" button. While the partition itself was already resized, the moving of the file system itself had not begun moving (it was in a 'read-only' phase of the process at the time), and so I am still hopeful that it is still possible to recover the file system, and that everything should be intact. However, it is inaccessible by any means I can think of, and located somewhere in the middle of the new partition, though I don't know exactly where.

Is there any tools I could use to find the location of the file system or recover it or really, just anything to get access to my files there? Any help is appreciated.
