SD Card compatibility issue?

Befor you can't get them anymore...prices have dropped, so no reason, not to get 2-3 more of them:

Lexar have been bought by Longsys. https://www.dpreview.com/news/5923190395/lexar-acquired-by-chinese-flash-storage-maker-longsys. They are going to provide continuing support for previous products. Therefore if they are currently being discounted, even more reason to buy now.

In a Leica Store this week exchanging my M10 and was told do not use Lexar cards. Since they knew that I also own a M240 they also said don't swap cards between the 2 cameras. All I own is Lexar cards. No reason given but they were very emphatic.

It sound more like hearsay when they can't give a reason.

I thought the SD card incompatibility on the M10 was supposed to have been sorted by an FW update - or isn't it? Apart from the floppy write lock switches on my various Lexar cards, which need super-gluing in the writeable position, I have found them the most consistently reliable of all the different SD cards I have had over the last 15 years (MMC cards before then). I have had a few problems with the SanDisk cards I was using before Lexar but when I got an SL, the Lexar UHS II cards were almost half the price of SanDisk and seem to work at least as well, if not slightly better. I never swap cards between cameras, without running through SD Formatter and doing a 100% clear as well as format, rather than just re-writing the FAT.

 

I would have thought that Leica or whoever writes their software, would purchase/licence the SDXC control software as a module from the SD Association, who set the standards, as SD Host Ver. 4. This would ensure that there should be no problems with reading/writing from/to any compliant card, up to UHS II and ADMA 3. If Leica cannot integrate this module successfully themselves, into the control software of their M cameras, which the various problems since the M8, would point to, maybe they should out-source this work to their partners in Japan, Panasonic. Panasonic have far wider experience of electronics and more resources. Whereas my wife and I have had various mechanical (lens extension) and sensor issues with Pana-Leicas, card problems have been noticeably absent. I cannot say the same about my digital M cameras.

I am using this Lexar SD-card since day 1 with my M10 and after a little more than 2500 shots, I have/had no problems whatsoever. The threads seem to report more problems with SanDisk-cards but then you don't know how many people using Lexar and how many SanDisk and then the group which uses others than the 2 fore mentioned...so IMHO I see no reason why you should not use your Lexar cards...maybe they wanted to sell you a card ?

Hey Wilson, 

 

Thanks so much for your detailed response. Unfortunately, even trying your suggestions, I am still met with the dreaded SD card error. Sometimes, the camera won't even recognize the card after multiple on/off resets, battery replacement, SD card re-insertions. I guess I just got really unlucky as multiple vendors have not encountered this level of problem after the 1.9.4.0 firmware update. I'll be returning the camera and putting myself in queue for a new one. Bummer, especially since the black M10 is in such high demand at the moment.

 

Hi SnowGolem,

 

I realize this is an old thread, but I just wanted to offer another possibility.. and that is the possibility that your card(s) may be counterfeit.  It happens more often than folks realize, even legitimate vendors are sometimes taken in.

I use both the Sandisk 64GB SDXC 95mb/sec and the Sandisk 64GB SDXC UHS-II 300mb/sec cards in my M10 without any issues at all.

 

Hopefully at this point in time, you no longer have any issues..

 

All the best,

 

Tony Bonanno

I propose a gentleman's bet that the '100% clear' (overwrite) has no particular advantage over a fast format, and in fact can slow down performance because bad blocks have already been tabled and because it adds wear, although not likely a lot. The advantage of a slow format is to find if a card is counterfeit or to make files reasonably irretrievable.

 

I am using this Lexar SD-card since day 1 with my M10 and after a little more than 2500 shots,

 

2,500 shots is not significant given that the failure is 1/100,000 writes or less unless the card is physically corrupted.

I no longer trust Amazon, after having been sent a batch of fake Duracell CR123A batteries. This was not a marketplace seller but Amazon themselves. Apparently they do not differentiate between stock from third parties and stuff they buy from manufacturers themselves; they all go on one shelf/bay. This means that fakes are totally commingled with the genuine and it is a lottery as to what you get. See here: https://consumerist.com/2014/05/12/does-amazons-inventory-commingling-help-fake-products-fly-under-the-radar/ Amazon will find that it is amazingly quick to lose a reputation and once they do that, they will be down the tubes in short order. They have only just made their first ever profit. Other online retailers will not be slow to spot an opportunity.

Had a similar problem with a B+W filter ordered from Amazon.  Can't remember if it was from them or a 'Marketplace' seller, but was obviously a poor quality fake.  Of course, they do take returns.

Sometimes a salesman will recommend something to make a sale but SD cards had nothing to do with why I was returning my M10. It was an unsolicited comment to inform me. I have had some cards go bad the last 20 years and I don't have anything against any brand. I trust Lexar and don't plan on changing until proven differently.

That brings up an interesting subject: How many customers complain? Supposedly the recent Equifax break-in stole over 200,000 individuals sensitive data and the data was specifically from persons who complained or protested charges.

 

Should we not wonder how many Amazon charges are similarly countered? I do. The bigger it gets, the more difficult it is to deal with until the public presumes it a new normal of incompetence.

Well.....I doubt that those who complain about problems with SanDisk have done that many shots...

I suspect a lot of SD card problems may be down to dust and dirt between the contacts on the card and those on the camera. An SD slot is an ideal collector for dust bunnies and fluff. I am sure it does no harm at all to give them a good blow out regularly and say twice a year put switch cleaner on the SD card and put it in and out of the slot a couple of times to wipe off any surface dirt, remove it, dry the card with a clean lintless cloth and blow dry the slot. I now have a HEPA filter on my Rocket Blower, so that I don't suck in any dust with the blower and then blow that into the very place I am trying to cleanws

A good idea!

[wlaidlaw]

A good idea!

 

Jac, 

 

It comes from a medical equipment supplier's catalogue that my wife had. I would like to replace the filter now (and get a new rocket blower) but I can't find the same filter again. She has changed medical supplier after the old one got taken over and the new one does not carry these filters.
