I'm surprised no one has suggested this yet but have you tried copying the files directly from the camera via the usb cable?

I thought I'd have a go. I couldn't open it in Preview, or Photoshop CS5, so I tried to open it in GraphicConverter. GraphicConverter is famous in Mac Land for being able to open lots of things even Photoshop will choke on. When I tried in GraphicConverter I got an error about 'file missing/folder missing', but the file still opened:

So, at least you know the images are still there! (That is presuming that the above is not just the embedded jpeg!)

I just looked at the sample file in a hex editor, and compared it with one of my own DNG files. I used XVI32 to look at the actual bytes.

In my files there is a section of the file near the beginning that has camera details and so on. In the bad one it looks like picture data right from the beginning. The file is still a DNG file, it has certain strings in there the same as mine, but the file itself doesn't appear to start from the right place in the data.

I suspect that the problem here is that the address table for the files on the card got corrupted, so the physical files as known to the system don't match exactly the correct file extents that are on the card. Trying to recover the files from the card correctly is probably the best bet, the data is all there but not attributed to the right files at the moment.

There is some Sandisk file recovery software that used to come with their cards, I used it once to recover some files that I'd accidently erased. Perhaps that's worth a try, but it only works if the card has not been written to after the error first occurred.

The jpg preview is (IIRC) a very small thumbnail image, and not useful for much more than its original purpose (i.e. as the 'icon' for the RAW file in photo album software)
