SD CARD INITIALIZATION FAILS

fat16lib:
This should not be required for the SparkFun shield unless you have a second SPI device.

Please run this program to get more info.

#include <SD.h>

#include <SPI.h>
Sd2Card card;
SdVolume vol;
SdFile root;

// Chip select pin for SD card.
const int sdCsPin = 8;

// Replace the -1 with the CS pin number of any shared SPI device.
const int sharedCsPin = -1;

void setup() {
  Serial.begin(9600);
 
  // Disable any other SPI devices
  if (sharedCsPin >= 0) {
    pinMode(sharedCsPin, OUTPUT);
    digitalWrite(sharedCsPin, HIGH);
  }
 
  // Try to initialize the SD card
  if (card.init(SPI_HALF_SPEED, sdCsPin)) {
    Serial.println("card init OK");
  } else {
    Serial.print("errorCode: ");
    Serial.println(card.errorCode(), HEX);
    Serial.print("errorData: ");
    Serial.println(card.errorData(), HEX);
    return;
  }
 
  // Try to initialize the FAT volume.
  if (vol.init(&card)) {
    Serial.println("vol init OK");
  } else {
    Serial.println("vol init failed");
    return;
  }
 
  // Try to open root
  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:
If there is a hardware problem with the shield or card you will see something like this:
If the card format is bad you will see something like this: 
Or this:
Please post the results.

hi sir.. i tried your code.. got error message as below, what does it mean??? pls help to solve it..
