I have had a problem with one of my fiancee's hard drives for some time now. Some how for some reason one of the hard drives shows no data, when it was actually her main data hard drive (mp3's, documents, videos, pictures, etc). Any time you click on it now it says "Hard drive not formatted. Would you like to format now?"

The hard drive was working fine like I said - I never formatted it nor has she. In fact I used it as the file back up drive while I was formatting a different drive (re-installed Windows XP). I'm afraid to click "Yes" to the formatting question because if the files happen to be there (where they should be) i don't want to risk losing them.

Anyone know of a solution that would get everything back? Any help at all would be great - a lot of the pics were pictures that we didn't have backed up anywhere else.
