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

[Nightly]

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?

Given that you can get the Extreme Pro version of that card for $12 on Amazon, and can get a 128GB Extreme Pro for $20, I would just ditch that card and upgrade. I wouldn't want to be using a damaged old 32GB card in my R6II. In fact, I would upgrade to UHS-II cards, if I were you. You can get a Sony Tough 128GB for $68 on Amazon. The R6II is fast enough that it's worth taking advantage of the speed.

Given that the R6 Mark II SD card slot is made for SDXC UHS-II cards that have two rows of contact pins maybe that missing piece is enough that the pins don't touch?? Maybe an upgrade is in order. Although I am not a fan of buying memory cards from Amazon, counterfeits, etc. I prefer Sony Tough cards, love their heavier build quality.

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.

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.

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.

The upgrade advice is good indeed, however the advice you have given is not related with my question. My concern is why a specific card working in all other devices doesn't work in this particular camera. As another user mentioned below - also experienced similar situation with his camera. I also tried an old 4GB Kingston Class 4 card - it worked on R6, which is expected to be. But it's not explainable why some particular cards are not working (in my case it was not detected at all).

I can't imagine how does two row pin design may result in loss in pin touch because of the broken piece on front surface. However for now it's the only estimation can be done because in other terms all other devices are same, except R6 which has UHS-II support. It would be very helpful for me to test the card in other R camera to see whether the outcome is consistent.

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

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.

I’ve used UHS-I cards in the R6II with zero issue. They’re backwards compatible. You just can’t use a UHS-II card in a camera that’s limited to UHS-I

Question for the OP is if they formatted the card to the R6II - but I suspect they never got that far if it’s not seeing the card at all. Also - don’t know if it matters which slot it’s in.

Actually both - cards and cameras are backwards compatible. So, UHS-II cards are also compatible with UHS-I readers. Just the speed will be limited to UHS-I in this case.

Yes you are right - as the card isn't detected by camera, the format is out of option.

Yes, I'm afraid I can't help you there. I did just try an old 32GB SanDisk Extreme Pro in my R6II, and it worked just fine.

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.

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.

 

[J.K.T.]

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.

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.

I have an R7, so it could be different, but I wouldn't expect that. All SD cards, old and new work in it, even the oldest ones.
The oldest slowest ones can of course affect performance, particularly high res video, but they work for stills, even if you can really see the difference in slow transfer to the card.

P.S. The V spec was introduced for Video, giving the minimum continuous write speed that video recording needs, and the camera can fill the whole card at that rate.
E.g. V60 : 60Mb/s
