Before you delete anything try a software title called EASEUS Data Recovery Wizard. Any version above 4.0 has a recovery wizard that will go through your RAW formatted disc and pull all the data off it. I had a drive that blipped into RAW format one day after a power outage...weird right? I had over 100,000 music files on it and didn't want to lose them and have to re rip them again.
Anyways, EASEUS worked. Try it out and see if your RAW formatted drive will cough up your files.
