I recently took some images of a girls soccer team. Upon opening the images in Adobe bridge, about 12 of 250 images had missing data. The "bad" images used different lenses, shutter speeds (from 1/8000 - 1/200), apertures, ISO and flash/no flash.
At first, I thought I had a shutter issue, but I would think that there would be some data in the "black area". For the heck of it, I opened one of the images in Photoshop, and the issue went away.
My second guess was that this is just an error while writing the embedded jpg to the NEF file? However, these errors didn't show up on the camera's LCD. Also, after opening the file, the issue goes away in bridge -- its almost as if it is being "fixed", but NEF files can't be edited. When I copy the NEF to a new location, the image is still "repaired".
Any ideas what is happening, or what could cause this?
(relevant camera data is in exif data for the second picture, approximately 70,000 clicks on a D3 body)
