I have a mystery with my external hd. I recently bought a new PC due to windows 7 ending soon. Windows 10 has been quite a challenge for a novice like me used to the simplicity of 7. However I have surprised myself by sorting out many things but this one is odd. My external HD contains a mix of photos & videos. On the old pc everything was there when I opened it but now on the new pc with windows 10 I can see all the videos but none of the photos. It is as if they have disappeared but if I connect back to the old pc there they still are. So they are on the drive but the 10 pc wont show them?? Help appreciated.
