there are ones under the sticker fyi.
there is a software called VirtualLab Data Recovery, it's the #1 product downloaded on download.com. I have used it in the past.

They do have a mac version, but the windows version is better. You can recover mac volumes with it. You can also image the disk from sector XXX to sector XXX very easily in the advanced options.
So you could get the data that is around the scratched area.
Basically what you have going on is a head crash. You would probably need to replace the heads and only copy a certain portion of the disk. But that isn't a job for someone who doesn't know what they are doing.
