I have a Mavica 300, it records on Mini CD-Rs. I recently finished a CD-R and tried to write a date on the back of the black finish, but I must have scratched the back a little with the White Pen I used to label the Mini Disc. Now my CD ROM won't read it. I have about 200 pictures on it. Is there anything I can do to get it to recognize the Mini CD-R and salvage the pictures.
