Hi everyone:
I am trying use the yundiskexpander.ino to expand my sd card divided into half/half but when i uploaded the sketch and running the monitor, it always showed me :

This sketch will format your micro SD card and use it as additional disk space for your Arduino Yun.
Please ensure you have ONLY your micro SD card plugged in: no pen drives, hard drives or whatever.
Do you wish to proceed (yes/no)? yes

Goodbye
