I own a Canon T3.  previously used a 32G SD card when my 8g was used up. now my 8G or 4G cards give me a "card cannot be accessed" why is that. I reformated the 8g but it still not working. they were working just fine before. Any ideas?

Does the 32GB still work? Every once in a while I get that error on my 1D Mark IV. Switching Off/On or removing/replacing card also works for me
