I shot a lot of photos during my summer vacation. Traveling during daytime, with little time to edit or review photos I often copied and erased my memory cards at nights so I could be ready for next day. When I took photos they looked perfect on my camera.

But after my vacation I began to see some ruined images like the one below. Horizontal black lines in different places of frames were in some of my images. Some were not even visible in Adobe Bridge thumbnails and I saw that when I opened those files.

My problem is why these files got broken? Is there a problem with my memory cards or the sensor of my camera? Or is it because I might have used cut/paste instead of copy/paste or maybe I shot too fast that memory card's writing speed couldn't catch up with me?

I'm using D800. Thanks a lot.

It looks like something went bad during the copy process. That could have happened in a few places along the line. It's won't be a speed issue though, files will either write or they won't. The only way you'll be able to find out what happened is to replicate what you did and check carefully at each step to find out where the corruption is coming in. –  James Snell Sep 1 '13 at 12:03

Don't know why this happened I'm afraid, but you might be able to fix the images in Photoshop, you can use the magic wand tool to select the balck parts and then apply content aware fill. –  Matt Grum Nov 9 '13 at 10:26
    
At a guess I would suggest a memory card issue - but it could be anything. Is the issue repeatable? Have you tried different memory cards? (Some troubleshooting to isolate the issue would possibly help.) A broken shutter definitely looks different - so it isn't that. –  DetlevCM Dec 9 '13 at 10:49
