T4i Isn't accepting any memory card.


Hello. I've had a T4i for over two years now. The camera has been completely unusable for more than 6 months beause it won't read any SD card I insert. I keep getting an error that says: card cannot be accessed. Reinsert/change card or format card with camera. However, I have tried multiple cards and when I attempt to reformat I get this error: Cannot format. Change Card. I'm at my wits end and really can't afford to repair the camera. Is there anything else I can do?



Have you physically looked in the slot to see if there's some debris inside?


SD cards have tiny plastic fins between each gold contact at the end of the card.  The fins make it difficult for something to short across two hold contacts (e.g. if you stick the card in your pocket and there also happens to be some coins in your pocket.


HOWEVER... I have seen these fins get damaged if the card is inserted the wrong way (e.g. label facing front of camera instead of back of camera).  It makes a bit of a mess and some of the bits of plastic can get stuck in slot.


If anything is preventing the contact pins in the slot from being able to make contact with the card, you'd probably get this error.  If you do see anything stuck inside and it doesn't want to fall out on it's own with a few taps, then you might use something non-conductive (like a tooth-pick) to see if you can work it free.    Be gentle.

Hi namesiwharas!


If what Tim suggested does not resolve the issue, the camera will need to be repaired.  To start the repair process, you'll need to complete a Repair Request on our website.

I had this same problem a while ago.  It was still under warranty and I sent it in, but they made me pay for it anyway.  Now it has happened again.  I have hardly used the camera in between these two failures - obviously there's some problem with it.  I can't imagine spending another $300 to get it repaired again just to see it fail a few months later.  I am really upset with Canon and can't see myself ever buying another Canon camera again after this.

If it is just a few months, your "warranty" paid repair is probably still under warranty.  IMHO, $300 bucks to repair a T4i is ridiculous.  You should be furious.

I should correct myself.  I was so upset about my camera not working that I posted before double checking the details.  The first time, the SD card wouldn't lock into the slot, whereas this time it does but the camera won't recognize any of the cards I tried to put in it (so it's not the exact same problem).  I had it repaired in February, so perhaps it was more than just "a few months."  And they only charged me $200, not $300, to fix it.  Nevertheless, they should have repaired it for free the first time, and the fact that the same part is failing again does not inspire confidence in the product or the customer support.
