Hi, I've tried all three to no avail. Both players display black with loud static. As for file sizes, they range between 300mb-2gb for a few seconds to a few minutes of footage. FYI, I've continued trying that repair program I listed above, and have now managed to get both the audio and video back, the only problem is the loud static also remains. Any suggestions?

I'm in the exact same boat. 5D3, 32gb card. Accidentally formatted. I used various recovery tools all give the same results, a .dat and .mov file. I've managed to recover the image using the Grau HD Repair tool - http://www.grauonline.de/cmsimple2_6/en/?Solutions:HD_Video_Repair_Utility , but that doesn't manage to recover the audio, creating a horrid static sound instead. Have you had any further luck recovering?
