Hosed my firewire drive...

Was playing around with Maestro, the software that they are using to control the Mars Lander, on my iBook and wasn't thinking when I told it to install to my external firewire drive. The problem with this is that the drive is formatted FAT32 so I can use it on my iBook, my Linux box, and a Windows machine. When OS X went to write to the drive it totally hosed the file allocation table. FAT32 doesn't support some of the file names that HFS+ does. Somehow this screwed up the whole works.

I _know_ the files are there I just can't see them. I'm looking for a restore utility that doesn't cost and arm and a leg. I found Virtual Lab which seems to do what I need but they want about $300 to recover the data. That's just to recover the files this one time. If I needed the program in the future I'd have to pay again. I don't think so. If anyone has any recommendations on software that might be able to un-fuck me, please leave a comment.

I'm most upset about the fact that the original of the video I made after my uncle died was one of the files that went missing. That archive means a lot to me and I want it back.
