my t4i will not read any SD cards

evanjamesmommy — Sun, 15 Sep 2013 20:39:29 GMT

When I try to take a picture, it says: "Card cannot be accessed. Reinsert/change card or format card with camera."

So, I try to format the cards, and it says "Cannot format. Change card."

I have used both these cards before and never had a problem, this just happened all of the sudden.

I even tried re-formatting the cards on my computer, but no luck.

Hi evanjamesmommy!

Thanks for posting on the Canon Forum!

At this point, your EOS Rebel T4i will need to be serviced by our Factory Service Center. To start the repair process, you'll need to complete a Repair Request on our website.

frankie_tan,

The EOS Rebel T4i will work with 16GB cards. However, not having tested them all with the camera, we are unable to guarantee that all 16GB cards will work the same. Even though other devices work with your card, it is still possible that the card itself is the cause of the issue here.

Have you tried other brands and speeds of 16GB SD cards?

I hope both of you folks have tried several different, brand new, top quality cards first?

Do not use cheap SD/SDHC cards!

Also if you use your computer, make sure you have formatted it as FAT32. If you have formatted it as NTFS

your camera will not be able to use it.

And you must use the correct card for your camera model.

Double post is on purpose!

Both will receive email notification.

Also keep in mind that cards DO wear out. The process of "writing" to a memory card is physically destructive. A card can have a defect that passes factory testing only to fail on the consumer after a short time.

Specifically which brand/model cards are you using?

Make sure you are inserting the cards correctly... label facing back of the camera. Gold contacts facing front (and going in first).

i am experiencing the same case with my rebel t5i, my camera body cannot access the memory card. i did reinsert the memory card, put a new memory card, and my camera won't reformat the memory card. i also tried to reformat my memory card using my mac and it didn't helped either. it seems like the memory card slot is not working. i already filled out the repair request form and they acknowldeged it.

i just bought the camera last october 30, three weeks ago. will i be paying anything if something has to be repaired or everything is covered by warranty? how will it get to the service center, if ever?

I don't think I'd hold my breath waiting for "evanjamesmommy" to click the button. It's been more than two years since she posted to this thread.

This seems to be a common problem with canon cameras. I have had my T4i for three years now and today is the first day it will no longer read memory cards. Have tried 3 different cards all have the same result they will not work in the camera.

It sure is a problem. Same thing happened to me, in about the same timeframe. No wonder it was a cheaper camera than its comparable competitors -- shoddy components. There is no way the card reader should fail so for so many people, without any damage or abuse to the camera whatsoever. More like a scamera.

You know that thread is 6 years old?

Of course I do, but the need to vent never grows old.

Re: my t4i will not read any SD cards

ebiggs1 — Mon, 26 Sep 2022 13:51:44 GMT

And, that the T4i has been out of production for 10 years?

Re: my t4i will not read any SD cards

yoitscoach — Tue, 11 Oct 2022 13:03:46 GMT

Of course, but if the camera has had light use, it should still have the capability to read an so card. Your comments do little for the situation other than pointing out obvious, yet not insightful facts. Ever tried helping anyone here or do you just enjoy trolling too much?

Re: my t4i will not read any SD cards

ebiggs1 — Tue, 11 Oct 2022 14:43:04 GMT

Facts, just the facts. The first comment was to hint a suggestion that you start your own new thread that is not 6 years old but apparently it fell on deaf ears. The second was to offer, repair by Canon is probably not going to happen on a 10 year old out of production Rebel.

"Ever tried helping anyone here or do you just enjoy trolling too much?"

I'll keep that in mind. 😉

If it was truly your intention to help with your original reply, simply add, "so you should probably start a new thread to get more replies" or words to that effect, not just state that the thread is 6 years old. Otherwise your comment could easily be taken as just mocking a lowly "Apprentice" who has not yet achieved the lofty status of "Legend".

I also have this problem with the T4i. It's been getting progressively worse and now it won't recognise any of my SD cards, or new ones listed as compatible. What do Canon do to repair this? Has anyone managed to fix this themselves? I've tried keeping the camera in an airtight bag with moisture absorbing silicone beads for two weeks, in case moisture ingress was causing the issue. I also tried cleaning the SD card and SD card slot pins with 90% isopropyl alcohol, to no avail. It's surely out of warranty by now - it'd be cheaper to buy a working used T4i or 700D for less than what Canon would charge me for a repair. I may open the camera to see if there's any physical damage to the pins inside the SD card slot next. I really don't see why this great camera should be added to yet another gigantic electronic landfill poisoning our soil and water supply.
