Well, I’m sure you know, that ‘reformatting’ is what did you in. Don’t do ANYTHING to it right now, and get professional help recovering the lost data. It may not be as expensive as you think. My father, who taught at a well known technical school, helped me recover my files in pieces some years ago. It may be tedious or it may be relatively easy for some but I’m sure its a common occurrence they’ve dealt with before
