R6 Mk2 Stopped Writing to Cards

[photopro]

Shot a wedding a few hours ago and reviewed photos after every couple shots, plus i reviewed some later after dinner and before shooting again. Over half of the reception is not on either card I reviewed images on the screen shortly after i shot. There were at least 300 images NOT THERE! the last file is timed around 830pm, i shot long after that. Its not the cards as i shot a few with the same cards after i got home and the images are there and visible in the camera and the computer. Also why didn't it record to the 2nd card? There's plenty of free space on both cards. I can see one card failing but not two and the failure is not repeatable, at least for the few shots after i got home to test them.   There is no gap in the file numbers.   Both cards are fairly new Sandisk 128gb. No fast shooting, single shots the whole evening which is normal for shooting weddings.  Since i was able to review them after shooting and not formatting or any camera settings were changed where are the files?  I record JPEG to one card and RAW to another and have never in 20 years of weddings have i come across this.    I will run a recovery app but i am not confident.   THIS ONE IS ON CANON! I will be calling them tomorrow, inexcusable.... i will keep everyone updated.

PS NO the option for shooting without a card is OFF. If that is turned on you couldn't review images as there would be none. R6 Mk2 doesn't have an Erase All option.

thanks

Thank you for your prompt reply.  THE fact your reply addresses Canons lack of liability sounds like someone avoiding the issue by saying "it's not my fault!"  That solves nothing.  Makes me think this issue is more widespread than you care to admit. I have been shooting Canon cameras probably longer than you are old so i know i did nothing to cause this.  Here's some more data to chew on.  I specifically remember looking at images made on the camera, taken after the last time stamp of 830pm.  Distinctly remember the garter toss as i was pleased the flash recycled to catch both the toss and the  ladies stretching to catch it.  Also I have loaded the same cards in the camera this morning and shot and all the images in the test are there.  It's as if the camera wrote to the cards, and then erased/deleted/ lost them.  It's not the cards.  Usually a corrupt card will prevent writing or take a long time to write.  

Again, Canon, what happened to the data ON BOTH CARDS, as my tests show no card error?

This is a public forum. I wanted to state what we know as a fact to the public. 

When something like this has happened in the past, inevitably, it's been found that a setting was changed inadvertently, or the media malfunctioned. In the fifteen years I've been employed at Canon, I've never heard of a camera overwriting a card (let alone two), without explicit instruction to do so.

Our support team will be happy to troubleshoot this with you at 1-800-OK-CANON (800-652-2666).

Welcome to the Forums. 

I’m sorry to hear that you’re having issues with your gear. Did you delete any photos from the memory card?  

Under most circumstances, there is no harm in deleting the photo you have taken. But problems have been known to arise when you try to delete “from the middle of the deck.”

Were you using full size UHS-II cards?

I remember deleting exactly 2 images during some dead time during the reception.  It was a good shoot with little or no editing needed.   If modern digital cameras can't function when deleting a few images from the middle of a card why are they in business?  Why is the function allowed?    That is such a mundane function, it's not acceptable as a solution.   No settings were  changed, setup is the same as yesterday, the same as a shoot this past week, the same as I have been shooting for weddings.  And what setting would cause "ghost" images to review without writing to the card?  Shooting  with no card even if activated, would leave you NO images to review which was not the case. 

Most troubling when you saw images that are no longer there...

Cards were Sandisk 128 gb each fairly new and no previous problems with either.  One card being bad, maybe, but not 2.  Also in my experience I had a cf card corrupt in 2008 during a shoot.  It took a long time to write which was a clue it was corrupt.  Lost a few images, changed the card and never had a card problem over 6 digital cameras.

Sorry forgot to add; there were some previous images on both cards.  More on  Card1 which is setup for JPEG.  Slot 2 setup for raw and not as many images on that card.  Plenty of room on both.  Thanks, on phone with Canon now.
