Garbage Written To SD Card By Arduino Uno

Hello All,

I am using an arduino uno to learn how to do datalogging. I have been following this tutorial: Below should be my fdisk output on the partitioning of the SD card and what gedit does when I try and access the file.

Does anyone know what is going on? all data is being printed written as a string. I don’t know why it can’t be read by my computer. I can get the data from the SD card to be printed out on a COM port by the arduino uno. Any help would be appreciated. Thank you
