Canon 6D lost files

[angooseg]

So we are in Sun City South Africa and did a safari, I took my 6D and a 70-200 USF with a 2x teleconverter and we got some amazing shots... Until we got back to the hotel and the majority of them were corrupt and wouldn't open. Some would. but the ones we wanted were corrupt, does anyone have any idea as to how to solve this issue? and get the files back?

Don't use the card again until you can connect it to a PC with a card reader and use some recovery software. If you save anymore pictures onto the card it will make matters worse. With card recovery software you may be lucky and be able to get some of the shots back.

Bad luck, sorry to hear about it. I'm sure you have a spare card with you and PC.

Start by copying all of the photos you can off the card.  Are you running windows?

Try running chkdsk in read-only mode from a command prompt.  If errors are reported, you can run with the /f or /r switch. 

There's no telling how effective recovery software is going to be since there is a big different between actual corruption and deleting one or more files by mistake.  If other cards format in the camera correctly, the card with the issue should not be trusted for keepsakes until you can ascertain the root cause.
