Hello,
I have an Arduino yun for 1 year, I have already made many mount on my sd card reader for some time but I can not do it. The SD Card Reader is no longer recognized. I do not see anything on the sd card.
Could you help me.
Below are some orders placed:

Thank you for your help.

Sometimes the pin that holds the SD card is bent.
Turn over the Yun and look close inside - at the pins holding in the SD.

Problem solved:
This is a welding problem.
The welds are at the bottom of the card were ok.
But the two welds postures that are on each side of the drive had welds that were not contact. (Welding KB).
Welding right of the player is not used as maintenance but it serves as a contact (the little Tetre -). After making a solder only on the right weld the drive was ok.
When we put the SD card into the reader must be careful to put the card into the slot and not next (my stupidity).
Thank you jessemonroy650 you were in the right.

Problème résolu:
C' est un problème de soudure.
Les  soudures qui se trouvent au fond de  la carte étaient ok .
Mais les deux soudures de maintiens  qui se trouvent de chaque coté du lecteur avaient des soudures qui ne faisaient pas de contact. (soudure ko).
La soudure à droite du lecteur ne sert pas que de maintien mais elle sert de contact (peut etre le -). Aprés avoir fait une soudure uniquement sur la soudure de droite le lecteur était ok.
Lorsque l' on met la carte SD dans le lecteur il faut faire attention de mettre la carte dans la fente et pas à coté  (c'est ma bétise).
Merci jessemonroy650 tu étais dans le bon.
