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

[Nightly]

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.

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?

Unlikely there is some mechanical part to detect a damage. Not only R6 and R6 II, BlackMagic also failed to detect.

One user above mentioned it could be related with UHS-II slot, which sounded to me only logical reason so far. I couldn't read which BlackMagic model it was, so can't confirm did it have UHS-II as well.

I wonder why I didn't attach the image of broken card. It could be good to clarify what type of damage it is.

P.S. I had a better shot of the card, but it is somewhere in the disk. I couldn't find now. So attaching a mobile taken photo. It will give a better description about the damage.

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.

Thanks for reading and commenting the post. However my post was not about should I use/keep this card or not.

My question and the comment of this user is about cases when a specific memory card acts differently on different camera brands and models. In my case the card is not detected in mirrorless cameras but works in DSLRs.

So the advice about throwing away is not helpful and is not answer to question what is the cause for this. Secondly as it doesn't work in my mirrorless camera = I can't use it. As I'm not using the card, I am not risking anything by keeping it.

Thanks.

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.

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.

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.

I think the user and me meant UHS-II slots have designed differently, which might be case why it can't detect the damaged card.

In other words - all old cards are readable in UHS-II readers - which you mean and confirm and we all agree too. But this one has an edge missing ( I attached photo in response to one user above) and maybe the internal design of UHS-II readers has some other type of card detection mechanism which doesn't recognize the inserted card with broken edge.

I will underline that - there is no card error shown. Just the cameras don't detect there is a memory card in the slot.

Exactly - so the cause of the card issue is no that it is UHS-I, but rather that it is damaged. There may well be some additional detection sensor in a UHS-II slot, I have no idea. I might guess that if you fitted an identical Sandisk UHS-I card (to your's) that has no damage, R6 ii would recognise the card without issue.

My point was that the real cause is likely to be the damage, not that it is an older / UHS-I card.

The differences between UHS-I and UHS-II go well beyond simply pin-out. The controllers are different, the handshake is different, the voltages are different, the architecture is different, basically the language itself is different. It's not like just putting a larger spout on a jug of milk!

Obviously the damage that this card incurred was enough to prevent negotiation with the far more complex UHS-II reader/interface (in fact enough to disable all functionality), but not enough to stop the much more primitive UHS-I handshake in the older devices. Your testing confirms this.

And of course my earlier advice to you (or anyone else with a failing card) doesn't change a bit. ;-)

BTW, what card did you select to replace the bad one with?

Correct - all my old UHS-I cards work on R6 II. Also I guess that the reason why it doesn't work - is related with that damaged part. Want to understand what specifically causes this.

I attached this image to another post, will be adding here too. The broken part is related to plastic only.

I need someone know this well, to explain how the slot detects the inserted card. I tried before, but couldn't get an information about this mechanism. This might give an explanation to understand what may be different in UHS-II slots if so.

I didn't replace this card specifically - I have several cards, all are Sandisks.

It must have occurred to you that the forces that damaged the casing on this card may have also impacted the circuitry inside?

Like I mentioned above, UHS-II communication is much more sophisticated than UHS-I. An airplane with a damaged control cable may still take off and land OK, but sophisticated maneuvers would end up in... Splat. :-D

ps. As per my previous post, I very highly recommend the Sandisk Extreme Pro and the Sony Tough lines of cards. Never had an issue with either over the years.

I came back to this forum just to respond to this thread. Quite an interesting read. Many years back the company I work for tested a load of cards for reliability and readers too. All for a very different and specific use case. One of the things we did was see how much damage they could take an still work. Of particular note was small damage like this. In many SD card readers, pressure on the contacts is kept very light. This to prevent excessive wear on both the card and the contacts. The shape and design of SD cards it quite specific and well designed to align these pins well and repeatedly. However, damage in certain places can reduce or even eliminate that physical contact with the spring plates in the reader side. This all depends on the design of the reader, which are not all made equal, and cost doesn't seem to come into it. So it is easy to see how damage, particularly in the corners like this can cause a card to not work in some devices.

It was interesting doing the testing. Automated testing had cards subjected to 10,000 insertion cycles, temp damage. physical damage and more. Some cheap readers performed really well while some expensive readers wore out connectors really quickly. So it is not always a cost thing, just design choices.
