+ * This sketch was written in order to test the modifications I did to the SD card library
+ * as well as testing it's stability
+ * Created by Anatole SCHRAMM-HENRY the 12/12/2020
+ * 
+ * /!\ Do not forget to import the two reworked SD libraries in your Arduino librairies folder
+ * /!\ Do not forget to create a /TEST folder at the root of your SD card
