5D MKii Error CF

So what originally happened was I borrowed a card reader to load images that I later found out was corrupt. I didn't find out until I used the memory card back into my camera - busy, error CF, please format card. Go to format, says cannot format, change card. Ok. Change card (I have 5 Lexar's). Same thing. And again for all 5 of my cards now! Cards work on my old 40D which I had on me at my shoot this happened at. I was told to try and format the cards on my laptop.. I own a mac so I erased the partition under MS-DOS (FAT) on one of them and while the card seems fine on the computer, it's still the same error back in camera. Then I tried to format the rest of them, all but one would not read, the one that did (32gb udma7 bought this year) had an error saying the disk inserted was not readable by this computer, I clicked on Initialize and it brought me to disk utility where it said the name was Generic Compact Flash and capacity was 155gb?! Tried to erase partition, after a while it came back to say disk erase failed, unable to write to last block of device. There are no bent or missing pins in camera or my own card reader (not the corrupt one that originally started all of this) - everything was working perfectly fine before I used this card reader.. Is this an issue internally with the body? How could this be fixed?

Hi! So yes actually I did get this resolved. Basically what happened is the card picked up corrupt data off of the card reader which is rare but since data is stored in the pins it can happen. Then when it went into my camera it fried the motherboard. So it needed a new board and CF assembly. Thankfully my former workplace agreed to foot the bill for repairs, I think it was about $700 including the service through canon directly. She was good as new after that 

Not sure how that can happen, no data is stored in pins. They are just inert pieces of aluminum. But I am 100% sure that the CF assembly is part of the motherboard. It can't be separated, there is no possible way. My pic above with the damaged pin is the CF assembly on the motherboard. If someone doesn't know how to repair it, or if it's damaged beyond repair, motherboard replacement is the only option. I know how to fix it, but that by no means guarantees it will be a succesfull repair. If it fails, I'll be looking for another Mark ii with a bad shutter or something that's not motherboard related I can do a swap with.

Thanks for getting back with us!
