My Passport essential problems


I have got a very strange problem with my WD Password Essential and I would be very grateful if we can find a solution. I downloaded my pictures to my it for 2 months ago from my laptop and before 2 weeks ago I downloaded new pictures but this time not from my laptop but from the system camera directly. Now I see all the files but I can open and see the pictures which downloaded from laptop but I can’t see even can’t open the pictures which downloaded from the camera. Wondering what  could the problem be!!

Thank you in advance…



How did you copy the files from the computer to the drive, manually like drag and drop or did you use a automatic software?
