LEICA SL2-S SD CARD CORRUPTION

[Amie]

Advertisement (gone after registration)

Hello,

I have a Leica Sl2s and I used it on a daily basis for event photography, it has 2 card slots, one is a backup and one gets used on rotation going in and out of the camera - which I then put directly into peoples iPhones using a USBC or lighting to SD card reader cable - and on the odd occasion the SD card goes to an error when putting in peoples phones and the images are all lost... I don't know why this keeps happening they are brand new SD cards from Sandisk why is there an error? 

 

Just for context I use the Sandisk Extreme Pro 256GB V60

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

Does this happen as well when you read out the card in another way? In any case I would format the card before using it after it comes out of a phone -you never know what is written back onto the card by the phone.

I don't understand your usage. Do you mean that you keep one permanently in the camera? Never reformatted?
What do you mean that the other is used in rotation? Do you have a third SD card that you use alternately with it?
Which cards do you reformat and when? After every event?
If one card is a backup, do you mean that the images on the card with the error are only lost from that card - never lost entirely (because you have a backup)?

Sorry for all the questions, but it might help with diagnosis.

A few comments.

• I would never put a card back in the camera for reuse after being in touch with an Apple device; they drop their own files on every drive they see (like a dog lifting its leg on a lamp post). As a minimum I would always reformat it in camera; I often reformat on a computer, but always on my PC, not MacBook, for the same reason. When on holiday with just my MacBook, and I have no choice, I set the SD card to Read Only.
• I always reformat cards after every event - usually in camera, but occasionally on the PC, using SDFormatter.
• I also photograph a lot of events (with the SL2-S), though I don't distribute images as you do (edit at home in Lightroom, then put them online for downloading). My cards are almost identical to yours, but are V90, though I doubt this is the reason for your problem. I record like you with the second drive as a duplicate, but the cards get swapped around randomly as I take them out for reformatting. FWIW I have never had the problem you describe.

try locking the card before you plug it into some other device, then unlock it before putting it back in the camera

Android phones ( and Windows)   are no better for writing back. Locking the card before any readout is best practice in all cases.

I've never found any files on a drive after using in a Windows PC.

Does not sound like a camera problem.

Moving cards true different cameras or phones is not something I would do without formatting every time.

Sony, Panasonic, Leica, Apple, they all create a database and folders.

It does not sound right that they are lost, probably unreadable. You can use the iPhone to shoot into cards. I do this with videos!

Keep in mind that some phones are slow or the readers are slow; creating a cache read from the card will take some time.

I would try to read your card on a computer and see if the folders and images are there. 
If not, I use a mac software to recover them, Disk Drill.

Thank you for you response.

so for each event I format all SD cards twice I leave one SD card in Slot 2 the whole time which I use as a backup and then I have 2 SD cards in rotation in SLOT NO.1

I reformat my Sd cards after every event yes!

Yes images aren't ever lost entirely because I have the back up - however because I am putting images from SD card directly in their phones I don't want to use the backup for this as I have to send all images to client after so I can't risk a corruption on the backup - if that makes sense.

 

Unfortunately for my job I have to dispute images directly to peoples phones as fast as I can as there are so many people and not loads of time.

 

I think this is weird as I've had my Leica for 1.5 years and I previously uses cannon for a few years and I used my cannon in the same way/ live transferring photos and never had any SD CARD error issues...

Have you looked for hidden files?

I just find it strange as this has only happened within the last year and I have been doing the SD straight into phone transaction for years... so I wonder why now..

Do you think it could be the USBC - SD card reader that is the problem?

[jaapv]

That is exactly what I was going to post right now as a possible cause.

what about the USBC - SD CARD READER? you think it might be that corrupting it?

Are you saying that the 2 cards that are in rotation have the same issues?

PS canon has a very simple structure and can't cause too many issues. Sony, on the other hand, is one of the most challenging.

It might even be a wonky contact.

Yes im saying the 2 cards in rotation are causing the issue....

oh so you think Leica is more complicated than cannon so causes less issues?

what does that mean?

I should buy new cables?

I would inspect the cable or the card reader
