SD.begin(10) keeps returning 0

Hi, I am trying to use the Ethernet Shield to open my SD card. But it keeps saying “Initialization failed” as in the code. Attached is the code. I am using an Arduino Uno R3.

test_2.ino (460 Bytes)

Why pin 10, isn't the SD normally in 4? (PIN 10 being used for Ethernet)

Thank you. I fixed it. :slight_smile: :slight_smile:
