Cannot Copy Files from CF Card
I just finished a photo shoot and have encountered a very odd problem. For background, I shoot onto 8gb CF cards using a Canon 5D Mark II. Typically, I copy the files from the CF card directly onto the hard drive of my Mac Pro (2.8 GHz, 6GB memory, Mac OS X 10.6.8). I then back up the files and import them into Aperture for post production. Last night, because I had back to back shoots, I tried to import the files into Aperture (Version 3.2) directly from the card. This is where things went south. Aperture indicated that it could not import about 1/2 of the files. When I look at the files on the card, the files which caused problems initially appeared as blank white images. I pulled the card and placed it back in the reader and now I can see the image on the card but cannot import the images into Aperture nor can I copy them directly on the hard drive. In addition to that odd behavior, when I look at the potential files for import on the card now using Aperture, they all appear as the proper images (whatever I shot), but I cannot import them. I am at a complete loss, and of course these images are for a client and the shoot is not repeatable. Any help would be awesome and help to keep this client who will not be happy that the shoot has been lost due to potential computer error. So essentially, I can see the thumbnails of the images on the card, which makes me suspect that they are there and uncorrupted. But I cannot move, copy or import them. Ideas?
