Hi, I'm sorry I don't know the answer to your problem. I had the same problem and I was wondering if the files may have gotten corrupted or something, I did not know.I thought it was the cheap camera I was using. I just deleted the ones with the gray bars and went on. I think it happen during the transfer of the files from from my computer to the external drive.
