Corrupted images captured with EOS R5 Mark II and certain SanDisk SD cards

That's a very good reason!
I bought all my Sandisk cards for exactly the same reason, and experienced not one single failure in 12 years.
Yet, what I read about the Sandisk SSD convinced me to get some Samsungs as backups for the backups...
Anyway, my post didn't refer to your answer, but to JWest's original statement. :)
Same here, since 2003 my Canon’s have recorded more than 500k pictures on Sandisk CF and CFE cards and have never had a failure. One CF card survived two cycles in my washing machine without a problem:cool:.
I have a Sandisk external SSD for my laptop which is not affected by the problems Sandisk has had with their SSD’s. Sandisk made a mess when the problems with their SSD’s surfaced, by continuing to sell them, at reduced prices, rather than acknowlegde and fix the problems.

Which brand of washing machine do you own, a Miele?
PS: Formatting is an easier way to get rid of dirty pictures...:devilish:

Sandisk used to be the company where the card firmware had the least amount of surprises and very good control of their supply chain, it was rare to get counterfeits when buying through a bona-fide distributor.

A few years ago their fastest line of cards wasn't so fast anymore, but still more expensive than others. I switched to Sony Tough cards, shortly after Sony did a recall for exactly the same issues. From my small sample size, Sony Tough (both SF-M and SF-G) have shown no issues yet, OWC and Sabrent cards have been drama free as well so far.
I have exclusively used SanDisk for my 10D, 50D, 5D3, and 1Dx (1G and 32G) since 2004 and never experienced problems either. But that doesn't mean that others haven't had problems.

For the R3, I got a pair of Sony Tough G's (128GB) and so far (1½ year) they have been rock solid. I virtually never format my cards in the camera and have never seen anything I could related back to the card just being emptied in the computer and not reformatted.

Is there a reliable statistical proof they fail less often than the other brands, or your personal experience with them?
As stated, my reason to go with those two were for the clearly more sealed construction method. Them taking time effort to do that also made me feel like the rest of it would also have more care taken, which may not be true at all LOL

I miss using the Microdrives though because they were such a cool little step in the evolution of digital media.

Remember this?
https://petapixel.com/2020/06/15/so...se-popular-sd-cards-can-corrupt-your-footage/, official recall here:

Curiously also V60 and V90 speeds.

And here a CR thread where a CF Express "Tough" card unexpectedly cracked: https://www.canonrumors.com/forum/threads/cfexpress-card-cracking-in-r5.40749/

You can't really know unless you wait a few years.
For the record, I use both Sony Tough and Sandisk Extreme cards and have not had any issues myself.

I know, if you are anything like me, more input often nets better results. I was just offering my sentiment on the matter.

I bought 2 of these. On my R5mkii, about 1 of 15 images are reported on Lightroom as "Corrupted and unusable". This does not happen with my other memory cards.
I contacted Sandisk. They said they will replace them, but the conditions are that they have to be in original packaging when returned. How do you think I know there is a problem if I never took them out of the package?
I think Sandisk does not stand behind their product, and does not intend to replace them.
They did not asked me to send back with the original packaging, other than I've send it back 1st before getting a replacement.

The only issue I had was that their RMA department send me back the exact affected model which was affected. Now I have to wait for the customer service for a follow up reply.

I had a new problem with a SanDisk V90 UHS-II card. I could not upgrade the firmware on my R5 ii untill I removed bthe Sandisk card!! Then it was all OK!
If you mean the problems with the firmware 1.0.2 update, this has nothing to do with the Sandisk SD cards: this is a bug in Canon’s firmware update preventing the update when there are two memory cards in the camera.

See: Post in thread 'Canon has released Canon EOS R5 Mark II Firmware v1.0.2'

Microdrives like these? https://en.m.wikipedia.org/wiki/ZX_Microdrive
I had two eventually. Finicky little bastards but a giant step forward from cassette tapes.

Eventually not just SanDisk cards?

I just came back from a photography trip to Scandinavia and we had two Canon R5 Mark II and one R5 equipped with Angelbird memory cards.

Both R5 Mark II:
AV PRO SE CFexpress 1 TB
AV PRO SDXC UHS-II V60 1TB - around 20% of images corrupt from both cameras

R5:
AV PRO SE CFexpress 1 TB
AV PRO SDXC UHS-II V60 1TB - no issues

SD Cards likely come from different batches as we bought them separately.

The cameras were configured to write RAW onto both slots for having redundancy. There was no error message when writing files, but trying to preview pictures from the SD card within camera resulted on errors and when removing cards and putting them in different readers, the two SD cards from both the R5 Mark II have images corrupted. Adobe software will just display an error, Window preview will load a portion of the picture and then display garbage for the rest.

I assume some of us mainly work with CFexpress and just keep an SD for ease of mind, but never really check data on it. For me, it was just coincidence, my camera was configured to read from SD slot for monitoring and this is when I realized there was an issue. I find it unlikely that both the SD cards in the Mark II fail and the one in the R5 works fine. I still want to do some more testing e.g. by switching SD cards from the Mark II to the predecessor and vice versa, but with those news about the SanDisk V60 cards having compatibility issues, my alarm bells kicked in.

I reached out to Angelbird already with a ticket opened on Sunday, but still wait for a response - in all fairness I don't expect them to answer within one business day.

2 different cards brands, same issue...
Could it be that the R5 II is the issue, and not the cards? :unsure:
