SD card problems!

[Darkirax]

Hi!
One day to another the SD card stoped working! I've read other threads but any of them worked for me...

I've stoped Dropbox, I've tryed to unlock the inside of the sd card just i case something was stuck..

This is a Macbooc Pro 13" mid 2012 with OS X 10.9.4

Anybody knows how can I do?

SD card problems!

Have you tried a card reader with different card?

 

[Darkirax]

yes! I've tried 5 diferents SD cards from diferent brands and diferent sizes and all of them work on other devices.

Reset pram and smc.

I'm trying to reset de PRAM with cmd+alt+p+r but instead of reseting it enters to a menu to recover a previous version of OS X. How should I do this reset?

You're doing it right. Maybe your alt does not work. Have you tried other side of the keyboard?

Also can you check system profiler if card reader is shown there.
