Canon EOS 100D problem//help!!!

[graceoiscott]

I am currently doing a portfolio and took pictures this afternoon (multiple pictures) but every 30seconds to a minute my camera would stop allowing me to take pictures and come up with 'Err 02. Card cannot be accessed. Reinsert/change card or format card with camera.' so i reinserted my card, many times, and after i finished taking the photos, i tried to look at them and there were none. Just now whilst i was trying to see what i could do to it, i took a picture, of the floor, and then tried to veiw it, that worked but then when i tried to delete the picture my camera started beeping, i turned it off to stop the beeping and when i turned it back on the picture had deleted itself, this happened again but i left it on instead of turning it off when it started buzzing and it cameup with Err 02 again and deleted the picture. Please help as i am doing a photoshoot for my media project tomorrow and really need my camera for it!!!!

Thank you!

When you refer to it as a sim, it makes me think you're using a cell phone card with an adapter. If so, that's likely to be your problem. Try switching to a full-size SD card.

Make sure that you format ANY new SD card in the camera, prior to use.  Never use a micro-SD card with an adapter, either.  Stick to the major brand names, like Lexar or Sandisk.  The ideal memory size seems to be 32GB, or less.  

Not every camera seems to like SDXC, >32GB, cards.  Most SDXC cards are UHS this or that compatible, which is exactly what your camera does not need.

Thank you! The SD card I was using was a 64GB which was obviously why it wasn't working, I have switched to a 16GB which works perfectly.
