I have ran into an interesting solution to a problem I see some people experience - corrupted Raw files with yellow or pink or orange horizontal stripes across the image.
I had this happening to me 2 or 3 times, completely random, long after the images were transferred to a HD, processed, posted and therefore wiped off the CF card.
Yesterday, I needed a couple of my old images that were kept in RAW in Lightroom and to my disappointment they were corrupted.
I've tried opening them in Photoshop, in other application hoping I maybe able to extract JPEG, but nothing worked.
Then, I've tried opening it in DPP 3.7 and when I opened those files in Edit mode, they looked ok. So, I've created a copy of one CR2 file, imported it into LR and then, lo and behold, it came unscathed. I couldn't believe my eyes, so I opened the second corrupted file and just saved it on top of itself in the Edit mode of DPP. It worked!
I couldn't be happier! 
I can't promise it'll work 100%, I don't even know it'll work on your computer, with your corrupted files, but this is just another possible solution that might recover your files.
Cheers
