Need help recovering data from a harddrive that started reimaging process

I have tried many utilities and file retrieval programs with varying successes, but once you have overwritten the FAT, and have copied over files, your goose is cooked, and you will most likely be stuck without your old image. I have yet to even hear of someone who has rescued files after going as far ass you have......Sorry for the bad news, but some things just don't have a remedy.....you just need to move on, and learn from it......Imaging programs usually ask if you are really, really sure that you want to run the image.....say no, then make sure you can say yes.
