A memory card working in Canon DSLR, isn't detected in R6 II

[Nightly]

You wrote the damaged card was UHS-I. What other marking does it have? C-speed class? U-speed class? V-speed?.

If it doesn't have the last, it would fall into same category as mine ... with the exception that the problem might not be with just UHS-II, but all early UHS cards. Of course, in your case it could be the damage too...

Does anyone else in this discussion have UHS cards - preferably UHS I and UHS II - without v-speed class to test in new cameras? That would be interesting. If they worked, it would not be a general problem. On the other hand, if they do not, all you'd need to do is to check for the v-speed marking in UHS cards.

The designations on it: C10, U3, V30.

I tested pretty old 4GB SDHC Class4 without any designation - and it worked. So it's not reasoned by old generation.

OK - thanks! As yours had V30, the reason should be something else in your case. Mine could still be an incompatibility in early UHS-II card.

In my case I had a Lexar SDHC UHS-II U3 card that worked perfectly in 7DII, but wasn't recognized in RP, R7 or R5II. There was no apparent damage on the card either. I still have no clue what that was about.

That's exactly what leaves me worried - why a specific card working in all devices doesn't work in this R camera? I haven't had a chance to test in another R camera. Ttesting might give some explanation. But now at least I know that similar case happened to others as well.

Are you actually worried about it or just curious? It doesn’t seem to be worth worrying about…

If any card may stop or not work in this camera without a reason caused by a memory card is worrying. In case you get a card and it doesn't work with no reason, then you item is useless. It will not be covered by warranty, nor returned. Also means anytime you may get in a trouble being left out of memory.

Ok, but in your case you know your old card is damaged. Why not just get a new one? Get two! It’s always possible you will get a lemon, but that doesn’t often happen in my experience.

I know. I have and using undamaged ones. This one is damaged on exterior, but not memory itself. It makes me think - why the camera can't even detect it, while other cameras and card readers read and write without issues. Doesn't it arise a question for you?

After having to deal with SD cards in a product, I've started replacing cards at the first sign of trouble. As pointed out by others, a 32GiB card is relatively cheap to replace, for me it would outweigh the frustration of not being able to shoot and/or loosing pictures.

Sony Tough cards (both the G and M variants) have been very reliable for me the past years (post recall!), but more expensive.

Heh. I'm not frustrated with this card itself. I used CF cards on 5D IV. After moving to R6 now can't use it and I am back to SD cards again.

I generally favor Sandisk in memory so in the past mainly I bought Sandisk brand. Having said that my CF is Kingston which I'm happy with for many years. It's my 3rd Sandisk card which got into an issue. First one got locker piece broken. The other one had some errors on it, which I don't remember what exactly was. Not sure due they break because being fragile compared to CF or because Sandisk produces them from lower quality materials so they fall apart.

As others have said, the card you are worried about would cost under $20 to replace. If it were me, my images are important enough that I would not risk losing a single one for $20. Just buy a new card and throw the damaged card away.

A U3 rated card is not UHS-II.

Having said that, I have many older SD cards of various speeds, and all seem to work equally well in my R bodies and even my Sony RX100v. What is important is to format the card in the camera.

Interesting. The card does have two rows of pins, "SDHC II" marking and "U3" marking, so what is it?

Edit: I'll check if it had V-designation as well.

Mea culpa. I was wrong, apologies for causing confusion.

No problem - I learned something new.

UHS-II was introduced in 2011 at 4.00 version of the standard.
U3 was introduced in 2013 at 4.20 version of the standard.
V-speeds were introduced in Feb. 2016 at 5.00 version of the standard.

As it happens 7D ii came in 2014, which fits the time slot after U3, but before V-speeds, so that explains the lack of V-speed marking.

I can only conclude there is some incompatibility between that standard version and current implementations. Note the implementation as opposed to standard! The latter is supposed to be compatible. Could be some shortcut taken, which ignores the old standard version.

It's worth pointing out that while these cards will work in UHS I cameras like the 7D Mark II because they're backwards compatible, you will not be getting UHS II speeds and there's no performance advantage in using them. When I had a 7D Mark II I just used the highest performing UHS I cards in it.

Quite true. I bought it thinking about using it in future with other cameras. That didn't quite work out.

Hi. You are right. However my concern is not about that. It is related to reason and cause for this. That also means in future any card might get "unreadable" by camera in false way, while it is still in working condition.

Want to give some update/follow up.

Months ago I took it to a shop and asked to test the card. The only available mirrorless camera was Canon R6 (not II). It also couldn't detect the card.

Nikon - DSLR detected card as like my Canon DSLR.

Blackmagic - couldn't see the model number, but also seemed to be mirrrorless - similarly also not detected the card in any slots.

It's still unclear for me why or how mirrorless systems fail to detect it.

I have a Sandisk Extreme Plus 32GB SD (UHS-I) memory card. The card is working in Canon 5D IV, and in memory card readers. However it's not even detected when put to R6 II. It doesn't say there is a memory card error, but says "No Memory card". My other card is working fine on this camera.

Need to mention that this particular card has some exterior damage: the front left edge plastic is broken, so the inside part is partially revealed. The rear plastic part of the card is okay.

I could assume the cause to be related with the broken edge, however the card is functioning and readable in all devices. How different could be R6 II card slot so that they even not detect the inserted card?

...That also means in future any card might get "unreadable" by camera in false way, while it is still in working condition.

Your card is damaged. Throw it away. You don't want to keep using it and then have it fail AFTER filling it up.
If you're worried about damaging a card in the future, then I'd advise purchasing a Sandisk Extreme PRO, or a Sony Tough. I've never had either fail or even hiccup no matter what type of device I've used it in (includes Canon mirrorless M5, M6, M6 Mark II, R5, R6, R7, R5 Mark II, And R6 Mark II). Over a million photos.

Bear in mind that most mirrorless cameras have SD card slots designed to take UHS-II cards. Your UHS-I card may have been damaged in such a way that although it can be read in a UHS-I slot, it cannot be read in a UHS-II slot. But as suggested elsewhere, throw it away and stop worrying.

Seriously though, my guess would be that mirrorless records video and video is way more demanding of the card.

Last time I checked the 5D iv mentioned by OP (and every DSLR in at least 15 years) also records video, so it seems unlikely that has anything to do with it ;-)

In a previous post you said that the cards exterior is damaged. Could it be that the R6 has a mechanical switch to detect a card and that the damage prevents it from being triggered?

Memory cards can be strange beasts. I have a Sony SD card, top of the range when I bought it and still a respectable performer, which fails completely in my 5D IV, spitting write errors all over the place, but works perfectly well in my 7D II. Seems to go OK in the 5DS and the r5 II also. But it hates the 7D.

That same card, also fails to work correctly in one of my three card readers. It has always been like this, ever since new.

Back when I used to work in IT, we used to have similar issues with finicky damn Sony CD and DVD drives. After various intermittent troubles with them, I instructed the Purchasing Manager not to buy any more Sony product; stick to Panasonic, LG, and similar. Result: no more problems.

Anyway, the card still works so long as I remember that it's fussy about cameras, and I have religiously bought other brands ever since. (Mostly Lexar, also Delkin and one or two others.) Not a single problem.

Same advice as to the OP. Get rid of the card! Memory is pretty cheap nowadays. Why risk it??

Choose whatever brand your heart desires. Just replace it.

No, the card is in perfect condition. It is just has compatibility issues, a design and test fault on Sony's part; there is no question of it being faulty or damaged. I currently have in in my new OM-5, where it works perfectly. And it's not about "what my heart desires", it's about the facts of what works and what does not work.

I think you are right - it looks like the answer is UHS-II slot equipped mirrorless cameras which can't detect it. As most DSLRs have UHS-I slots. Now I wonder what could be different in UHS-II slot making it inaccessible.

Well no. It's not related with video recording or video mode.

I thought I had posted it here, but perhaps another thread - in response to this (or similar) discussion, I dug out an old (2008 I think) Sandisk Extreme III 8Gb Class 8 SD card (obviously UHS-I) and stuck it into both R8 & R10, and both cameras were able to recognise the card, format it and write images to it.

So, I am still inclined to think that the physical damage to your card is the real issue, not UHS-I.
