SD Card not accessible and won't format

#1 Post by Gustavo » 22 May 2018, 11:22

My SD card stopped working while in the camera, there was some error while taking a photo and then I turned off and on, and next time it turned on it asked to format the card.

I inserted the SD card on my mac and it doesn’t recognise, doesn’t even appear on disk utility. But if I have the card inside the camera and connect the camera via USB then I can see in disk utility that it somehow recognises a 16GB drive but it is not mountable or readable. This is also the only way photorec/testdisk detects the card. It didn’t when inserted in the SD card slot.

I tried first using the photorec/testdisk with no success. I’m not even sure which one I should use but then I understood I could try to format the card and then use photorec to recover the photos.

But then I figured out I can’t even format the card. Not in camera and not anywhere else.
I even tried using the app SD Card Formatter to format it, but I get this message:

Code: Select all

Error

[ERROR] Invalid end of sector signature: 0x0000
[ERROR] fat_check_validate_boot_sector returned error: 22 (Invalid argument)
[ERROR] Initializing cached values failed: 22 (Invalid argument)
[ERROR] Generated invalid volume. fat_volume_create returned: 22 (Invalid argument)
Otherwise I ran testdisk but nothing seems to happen. After analyse, it doesn’t find any partition, Quick or Deeper search gives no results. Photorec doesn't find anything.




Here is the log for testdisk:

The SD card is physically damaged. You need to replace it.
If you really need to recover your pictures, you need to contact a data recovery company.

Ok, thank you.
What is the piece of information in the log that shows that?
Yes there are important photos inside. Do you have any experience of some companies that do this, should I send it to manufacturer (SanDisk) or something else?
I am in Europe, but if needed I could send it anywhere.
Thank you
