I've got a Canon EOS 60D that I've used for years without major issues, but recently it refuses to read any of my new SD cards. These are all Class 10, 32GB cards from reputable brands, and I've tried formatting them both on my computer and in-camera (when it recognizes them briefly). The camera either shows "Card Error" or just says "No Card Inserted." I even cleaned the card slot contacts gently with isopropyl alcohol but no luck. Firmware is up to date as of last year, and batteries are fully charged. I want to keep using this camera without having to buy an older SD card model or a new camera altogether. Has anyone run into this with older DSLRs? Is there a way to reset the card reader hardware or update firmware unofficially? Or could this be a hardware fault that’s repairable at home?

Sounds frustrating! The EOS 60D should definitely handle 32GB Class 10 cards without a hitch, so it’s odd it’s acting up. Sometimes, even if the cards are legit, the camera’s card reader pins can get slightly bent or worn over time, causing intermittent contact issues. Since you cleaned the contacts already, maybe try gently flexing the card slot door or reinserting the card a few times to see if it “clicks” better. Also, double-check if the cards are SDHC (not SDXC), as the 60D doesn't support SDXC cards natively.

If that doesn’t help, it could be a hardware fault that’s tricky to fix at home without proper tools. Some folks have had luck with a professional cleaning or repair service, but that might cost more than a used replacement body. Firmware-wise, the last official update was a while ago, so unofficial ones are rare and risky. If you want to keep using
