[qanda]This thread is about the Western digital AV 500 GB 7200 RPM EIDE. Click here to see full specs[/qanda]Copied all my JPEG and MOV files off my camera and camera card to WD backup external 500 gig harddrive. NOW, I cannot copy the MOV files to any other place on my desktop. Therefore the only way to view them is through the external drive, but if I want to edit or do anything with them, like simply back them up, the MOV file will not copy. I checked space. I have plenty. The error message says, “can’t read from source file or disk”. It copied the JPEG’s without a problem. These are my own movies from my camera, no copyright. I wanted to back them up since I deleted them from my camera. Now I can’t do anything with them because I can’t get them off this hard drive. Please help!
