EOS M cannot read or format card (over 200 pics previously taken on same card)

petewallace1959 — Mon, 20 Jun 2016 11:44:33 GMT

My relatively new EOS M (in which I put a 128GB ultima PRO X card in) can no longer read the card. The camera won't allow me to format the card either? The camera has been working perfectly previously and I've taken around 200 piccies with it without any problem?

Has anyone else had this problem?

I am not familiar with that brand of SD card. Let's hope that the card has failed, instead of the camera. Try a different card ,one with not as much capacity, 32GB or less.

What error message is the camera giving you? Are you attempting a "Low Level Format"?

I've tried both a low level and a 'normal' format, the message I get when I turn the camera on is 'Card cannot be accessed Reinsert/change the card or format card with camera.

When I try reformatting the message I get is 'Cannot format Change card'

So I guess I'll try another (lower memory) card

Okay. Let us know how that works out. Make sure the door is fully closed, too.

I took out 128GB card (Intregra Ultima PRO X) which the EOS M told me it could no longer work with (although it has worked perfectly with for the last month or so), and I replaced it with a SanDisk Ultra 32GB card, which apparently, the EOS M is now all cozy with and it appears to be reading fine - fingers crossed 🙂

Did you ever successfully format the card in the camera, or did you just start using it as it came from the factory? If the latter, maybe it took the camera a while to realize that the card is too big for it to handle. In that case the card might start working again if you were to low-level format it on a computer.

... and then do a regular format in the camera, which causes it to create the default set of folders.

I've tried formatting the 128GB card in my laptop and it (the laptop) won't even recognise that I've put the 128GB card in the card reader. And I've checked that my laptop card reader is working by inserting the new 32GB card into it and it reads the 32GB card no problem so looks like the 128GB card is kaput 🙂

Well, I hate to say "good", but good. It's a good thing that it appears to be the card, and not the camera.

Ditto, it had me worried yesterday 🙂

I don't think you have to format the card to get it to create the folders. A camera will often create a new folder if it sees a card that has been partially written by another camera.

Maybe not, but formatting in the camera will also "erase" any existing folders on the card. It's also probably a good test to see if the camera can work with the higher capacity card, or not.
