Had a hard drive go south prior to backup of a wedding. Am in desperate need. Recovered from original media card the CR2 files I shot; was near 800 in all. All but 100 of them are corrupted as recovered from the CF card. They are all recognized as CR2 files in Explorer and even have the correct file sizes. But neither Lightroom, Canon Photo Utility, Photoshop or any other editors will open them. I've tried ExiftTool to extract JPGs, got file format errors. I have a Hex Editor but can't make heads or tails of what I'm looking at. I'm out of options and don't want to have to tell this couple I have lost their photos. Anyone out there have experience with repairing this type of file corruption that can do the work or have suggestions? PLEASE. Need help!!!!
