I have tried converting in Photoshop CS4, Lightroom 2.6 and through the DNG Converter, but all have the same result. The image was taken with a Canon 7D, copied to the computer (running Windows 7 Ultimate 64-bit), converted to DNG with the original RAW file embedded. As you can see from the posted images below, the original and extracted .CR2 files are not corrupt and can be viewed/edited easily. Only the .DNG file is having issues. This is happening sporadically, and of the couple hundred images I have converted, it has only occurred to a handful. However, it always occurs to the same files (reconverting makes no difference). Any ideas?

Extracted .CR2 File (From the above .DNG file w/ CR2 embedded) - http://www.box.net/shared/cjz16arczc

I downloaded the extracted CR2 file and found, that it is corrupted. Then I downloaded the original CR2 file and found the same error. It is very natural, that the DNG file contains this error as well; if I load it in ACR, about 4/5th of the leftmost strip appears, and that's it, the rest is garbled.
This image is garbage. Check your card, the card reader/writer, the cable, the computer, the camera, whatever.
