Problem with Ethernet Shield SD Card

Other Hardware Storage

Please run this program to get more information.

#include <SD.h>
#include <SPI.h>
Sd2Card card;
SdVolume vol;
SdFile root;
const int sdpin = 4;    
const int ethpin = 10;
void setup() {
  Serial.begin(9600);
  pinMode(ethpin, OUTPUT);
  digitalWrite(ethpin, HIGH);
  
  if (card.init(SPI_HALF_SPEED, sdpin)) {
    Serial.println("card init OK");
  } else {
    Serial.print("errorCode: ");
    Serial.println(card.errorCode(), HEX);
    Serial.print("errorData: ");
    Serial.println(card.errorData(), HEX);
    return;
  }
  
  if (vol.init(&card)) {
    Serial.println("vol init OK");
  } else {
    Serial.println("vol init failed");
    return;
  }
  
  if (root.openRoot(&vol)) {
    Serial.println("open root OK");
  } else {
    Serial.println("open root failed");
  }
}
void loop() {}

If all is well you should see this:

card init OK
vol init OK
open root OK

If there is a hardware problem with the shield or card you will see something like this:

errorCode: 1
errorData: FF

If the card format is bad you will see something like this:

card init OK
vol init failed

Or this:

card init OK
vol init OK
open root failed
