I had a similar issue with my R7. The fact the camera locked up with different SD cards led me to suspect it was a hardware issue with my R7. Contacted Canon and they set up a warranty repair.

In your situation, were the SD cards usable in other cameras and/or recognized by your computer, etc? In the situation here the cards are unrecognizable (dead) after the malfunction.

If you still have that Sony 256GB V60 card in your second R6II, could you take a photo of the back of the card for me? I'm curious to see where it was made and if there is any similarity to the information on the back to the photo I found on Amazon, as well as the Sabrent cards I have.

Thanks!

Here is the Sony card that is currently problem free.

Thanks. I had a closer look at my Sabrent 256GB V60 cards - I currently have three. The one I bought from Amazon Canada on the day of the first failure (Sept. 24, 2023) has a different DVDN number from the two I bought from B&H in July 2023. The two replacement cards that Sabrent shipped to me directly from their Amazon Canada account, about two months apart, arriving in October and December 2023, have the same DVDN number as the two I purchased from B&H. I should have checked that immediately on receipt, but in any case, I've used both in the R6II so far without incident. That said, I also have not had as many intense, day-long events since then to really put the camera and/or cards under some stress.

I have the feeling it's a combination factors and it's going to be difficult to pin down...

I know of one way to have problems like this with any Canon body. Take it from a warm location like a car to a very cold location, unprotected. Condensation will form inside the body. It will show up as card errors before long. One guy did this so much when I was standing next to him that the card almost caught on fire.

R6II certainly is not super well sealed. On cold days shooting for a few hours, water vapor from my breath will get in and condense inside the viewfinder eyepiece. I never had this happen with the 1D series, understandably. One of the tradeoffs of going down a few notches from a 1-series to a 6-series.

The environmental conditions at the time of both my card failures were not such where condensation would have been a factor, therefore this is unlikely to be the cause.

Both however were image heavy with some intense shooting. More so the second one (football game), which had lots of CRAW bursts, often filling the buffer (100-120 files) at 40fps.

How much did this repair cost you?

Fortunately it happened in the first year so it was a warranty repair, though I always buy my equipment w/ my AMEX so AMEX would have picked up the tab if it happened in year two.

The cards were fine even in the R7 once I removed the batteries then reinstalled. But even if you situation is different it still seems like a hardware issue if it happens frequently especially w/ multiple brands/sizes/speeds and you are doing a low level format on them occasionally. You might try a card that Canon recommends or has tested just to cover your bases.

Well, it happened twice, which considering it was complete card failure, certainly was twice too often. But it's also not frequent and leaves me wondering what the root cause could be. That it happened with the same make, model and production batch number cards had me suspecting a bad card batch. But there could also be some hardware/software conflict that climaxes with card failure under certain conditions, or when a certain unknown threshold is crossed.

It reminds me of a problem with the Leica M9 where it could be pretty reliably triggered to fail writing to the card if image playback was turned on and zoomed in on images while it was clearing the buffer. It didn't result in card failures, rather write failures. That camera seemed rather finicky about the cards used in it.

I don't know if this applies (I don't shoot Canon), and it's not likely the problem, bit I've heard and seen that with some/many brands, if the card is removed while still being written to it can corrupt the card.

Honestly you kinda answered your own question in your original post when you wrote: To note - I have an identical Sony 256GB card in the other R6 Mark II camera body and it has experienced no problems..

If you have the same brand/model/batch card in your other R62 w/ no issues then highly likelihood the issue resides with your R62. Contact Canon (CPS if you have that) and get it fixed under warranty.
