But I also want to mention that Canon didn’t charged me anything even though it shows I tried to fixed. (Still under warranty)

I think the Canon site should have a page like this one for all the people out there having the same problem.

Once again thank you so much for having the time and effort to help so many people out there, greatly appreciated!

Keep up the good work!

even with the best cards, you can still get a bit of debris in one of the holes that could bend a pin.

always keep your cards in the plastic case when traveling them and be very careful inserting the card. make sure you are not sliding the card in sideways!

I am a commercial photographer of 25 years plus. I have used High end Leaf digital backs in the studio for 9 yeas and have had no problems whatsoever with them and they are used daily.

I was very impressed with the Canon service here in the UK. My camera was repaired and returned to me within 7 days free of charge. I made a point of speaking to the technician to ask what had been the problem as I was convinced I had done nothing wrong. He said it was pin damage causing a short which blew a fuse and the power supply thus protecting the rest of the camera from further damage.

I put it to you that this is a common complaint and an inherent problem with these multi-pinned flash cards – BE VERY AWARE and CAREFUL

Discovering the bent pin (Exact same pin position as your example), I tried to bend it back into place with a small tool. Well, the pin broke off completely. However, the card and camera now work. I can take and review photos. Makes me think some of those pins are not relevant.

Thanks for creating this site.

Anyways, I used a fine flathead jeweller’s screwdriver as a holder for a length of – wait for it – waxed dental floss! Basically doubled a length of it, making a tiny loop at the halfway point, then wrapped it around the shaft of the screwdriver. Used the loop to pick up the bent pin and lever it upwards. Once far up as possible I then used another fine flat screwdriver to bend the pin to as vertical as possible. Ever so carefully placing the CF card into the slot, the pins then shape up closer to true… hopefully they stay that way.

PS: I tried a pharmacy to buy a hypodermic needle but they wouldn’t sell me one (even took the camera in to show I wasn’t a junkie haha). I think this would be the best way to straighten pins if you a willing to try it, but I make no warranties!!

Thanks for the details outlined. I have a similar yet different issue with my 40D. I’m am about to attempt to straighten 2 pins that appear to have been bent and flattened. Thankfully, each are the at the extreme ends, and have bent outwards (one at each end of the pin set) so I should be able to straighten them out with a fine tweezer or something…

The reason I say I have a different issue, is that I was none the wiser to the problem. My camera worked fine for 2+ years and I had always used just the 2 cards (Lexar Pro UDMA 300x) that I purchased together with the camera. My suspicions arose when I had to use someone else’s Sandisk cards and none of them worked…

Canon tech here in Melbourne Australia hadn’t heard of the issue and they want min 2 weeks turnaound for repair that could cost me plenty since it’s not a warranty claim. Meanwhile, I need it to earn a living.

So I bought another Lexar Pro UDMA 300x today thinking I had a fussy body but it too gave error messages. If I damage the pins while trying to fix it, I can at least still use the 2 existing cards )
Wish me luck…
