Before I can unmount an SD card, do I need to call any function to stop it?
If I insert the card again, do I need to start it before reading from it?
If I have opened a file to write on the SD card and then remove the SD card, when I insert the card again, will I be able to just continue to write on the same file or do I need to reopen it?
I wish someone has answered my question about the whereabout of the SD library manual.
Once you remove the card the serial connection is broken / severed and you must re initialize the connection.
