Hi,
ABout this i 've no clue at all. But i usually have no problem so i guess it's not really bothering. Is it ?
In fact what you said before had a key word : phone. I thus plugged the phone (don't know why but wanted to have the card alone work) , and then the phone allowed access to the micro sd within it. I added music and pictures it was fun

Now, i'd like to understand why the card is not seen when in the external card reader, but the information i gave above.
WHat else can i do to get into it ?
Thanks
