Hi,

 

I'm new here so not sure how this is working, anyway I'll give it a try.

 

I have a D7100 and suddenly it stopped recognizing my memory card (Trancend premium 400x 64GB micro SD with an adaptor same brand) All was good but suddenly no good, meaning the camera does not accept the card anymore.

 

I work on a MAC and here I can read the card and store pictures so no problem here.

 

I erased the card on my computer and tried to do the same on the camera, but camera says the card is damaged??

 

So a bit puzzled on whether it is the memory card or the camera there have a problem. I do not have other cards to test with, so wanted to ask if anybody have any ideas or similar experiences.

 

Thanks in advance for any comment or ideas

Our cameras are quite finicky when it comes to memory cards. I wouldn’t be surprised if everything works again after a thorough cleaning of all contacts, both on the card and the adapter with de-oxit gold.

Nikon usually recommend cards from Sandisk, Lexar and sometimes Panasonic. There should be a list of what card they have tested in your manual.

I agree with Peter...cleaning the contacts might help but I would suggest getting and using supported cards...

Not sure if it makes much difference, but I tend to shy away from micro cards that require adapters to use with my cameras because they introduce another layer of complexity to the equation. That is, more contacts to possibly become damaged or corroded.

 

In your case, I think I would try a new card just to be sure that the contacts in the camera are in good working order. And, as my friends have suggested, I also think it's best to stick with Nikon approved memory cards.

I just had a malfunction on a new Kingston 16 GB class 10 SDHC 1 card, in my D7100. After 227 RAW files were captured it read FOR on the top screen, and the camera  would do nothing with that card installed until it was formatted. I was able to recover the files with a card recovery program on my laptop, but it shows only a very low compression thumbnail of each image, even though each file title shows average 27MB. I just now found out that Nikon recommends certain brands of SD card, from members in this posting. After formatting the Kingston card, it seems to work fine, but I'm wondering if the same thing will happen as the file count goes up again. Thanks,  Steve

The RAW (NEF) files includes both the full raw information, as well as a thumbnail for quickly browsing. So while you are currently only viewing the encapsulated thumbnail, the full information is still there but the file might be slightly corrupted. Some of the RAW editors might just be able to ignore this minor defect (no guarantee, so) but it is worth trying.

First you might want to install the most recent NEF codec

As regards the SD card it is a consumable - and nowadays quite cheap. While it might work properly after having been reformatted (chances are high), I wouldn’t trust it anymore, and therefore replace it (i.e. I consider my effort to take the captures a higher value than a low cost card.)
As the D7100 has two SD card slots I would use it in the second slot at best and select in the menu that the second card is the backup for the first one. (So, if it fails, it is only the extra backup that fails - and if it doesn’t, this option gives you an extra backup in case your first card fails).

Btw. Regular spontaneous in-camera formatting of memory cards, after having copied all captures, are useful for maintaining a clean filesystem on the the card.

Thanks Jerry, I will heed your advice, and dump the questionable Kingston SD card. and download the NEF Codec. I am new to Nikon just this winter, after many years with Pentax, so I can use all the advice I get. Thanks again

[Just_an_amature]

Thank you so much for the advices and I was not clear on NIKON only recommend certain brands. I will follow their recommendations as SD cards are not that costly nowadays.

 

Ron, I'll follow your advice with the micro SD ans keep it simple.

 

Thank you so much for all the advise much appreciated.

 

Fun thing is I have a D100 with 1Gb CF card still working as a charm, and that camera has been all around the world and never been spared from rain forest to desert. Why I would never go away from NIKON ~15 year old camera still working tell the story. -It even still runs with the original batteries!

Maybe your card is damaged. If there are important files on the card, you'd better recover them first or they may lost. You can also try Bitwar Data Recovery to solve this issue.

It might seems that the SD card is damaged but, this can be due to hardware issues as well. Therefore, check whether the card slot/ USB port/card reader is working fine.

Even if the SD card cannot be read using another handset or laptop, then your SD card might be faulty, and you need to replace it with a new one. Check out this article to know better solutions to solve such issue, Easy Ways to Fix "SD card won't Mount or Recognized" Error
