Hi folks. I'm having a problem. I've lost more than a few photos to this error and some are shot overseas and i dun think i'll ever be going back to shoot again. Can't edit or open with LR or CS5. It's caused by some errors when i transferred the raw files from my pc to my external HDD for storage. The thing i'll like to ask is, is there any way to repair and get back my NEF files again?
