Canon T4i Has a Favorite SD Card

[EverlyWyatt]

Hi Guys, I have a Canon T4i and recently it started exhibiting some weird behavior; It seems to only like 1 of my SD cards that I have tried in it. Its really stumping me because this card works 100% of the time as it should, but every other card I have/bought just does not work. Its almost as if I have a "golden card" that my camera is preferential to. The card that works is a San Disk Extreme Plus 64gb, I bought the same card new today and it doesnt work and neither does the San Disk Ultra 64gb, Ultra Plus 32gb, Extreme Plus 32gb. I have tried formatting all the cards on my PC and made sure that the camera is up to the latest firmware (1.0.5), no luck. Anyone experience something like this before, with a "golden card" that your camera exclusively uses?

Format the cards in your camera instead and try again.

Are these full size cards or mini cards with an adapter?

Where did you buy the other cards? Memory cards get counterfeited a lot.  They might be fakes.

I would only buy from reputable "bricks and mortar" stores.
