I have a micro SD card that was damaged, when putting in the reader of my computer, I got this

[65850.877706] mmc0: unrecognised CSD structure version 2
[65850.877719] mmc0: error -22 whilst initialising SD card

The card appear nowhere, and file /dev/mmc0 give :

/dev/mmc0: cannot open `/dev/mmc0' (No such file or directory)

The card contain a lot of traveling pic that I would really like to get back... Anything i cant try to do?

(the microSD card is in a new adapter, the last one was probably faulty and broke the card..) (on linux mint 18.3 64 bit)


Steps I would perform:

  • activate write protection on SD card
  • create an image of the SD card
  • create at least one copy of the image file
  • use recovery software only on the copies of the image file

Create the image:

List of software (collections) that I have used successfully for recovery:

  • Thanks a lot for the suggestion, but the sd card does not even show up in /dev :dd if=/dev/mmc0 of=saveimage.img dd: impossible d'ouvrir '/dev/mmc0': Aucun fichier ou dossier de ce type – Francois Sep 26 '18 at 14:05
  • Still there is hope, as this can be a problem with your card reader or the adapter. Maybe you can try a different (borrowed) adapter card that has proven to perfectly work with other micro SD cards? – Marvin Sep 26 '18 at 15:53
  • I will try that in the morning (but the adapter is brand new) if it show's nothing with the other adapter, if I understand well, it's mean that there is no work around? – Francois Sep 27 '18 at 5:49
  • Unfortunately I do not know how to recover the data, if all adapters and card readers fail to give (at least raw) access to the card. Although image recovery apps for Android devices exist, I can not recommend any. Those I have tested simply did not work. – Marvin Sep 27 '18 at 9:51
