Using the DFRobot SD Card Shield with Arduino Uno Rev 3

Ladies and Gents,

I am sort of a n00b and I would like some help with regard to reading/writing to SD card.

I have an Arduino Rev 3 and a DFRobot SD Card shield (513137). The instructions I am referring to are from "http://www.dfrobot.com/wiki/index.php?title=SD_Module_(SKU:_DFR0071)". I have connected my SD card module in the same manner, and I have copied the code exactly as is from the Wiki to the Sketch where I am working.

[code]/*
* Install the SdFatV2Demo20110108 library!
* Append Example
*
* This sketch shows how to use open for append.
* The sketch will append 100 line each time it opens the file.
* The sketch will open and close the file 100 times.
*/
#include <SdFat.h>

// file system object
SdFat sd;

// create Serial stream
ArduinoOutStream cout(Serial);

// store error strings in flash to save RAM
#define error(s) sd.errorHalt_P(PSTR(s))
//------------------------------------------------------------------------------
void setup() {
// filename for this example
char name[] = "APPEND.TXT";

Serial.begin(9600);

// pstr() stores strings in flash to save RAM
cout << endl << pstr("Type any character to start\n");
while (!Serial.available());

// initialize the SD card at SPI_HALF_SPEED to avoid bus errors with
// breadboards. use SPI_FULL_SPEED for better performance.
if (!sd.init(SPI_HALF_SPEED)) sd.initErrorHalt();

cout << pstr("Appending to: ") << name;

for (uint8_t i = 0; i < 100; i++) {
// open stream for append
ofstream sdout(name, ios::out | ios::app);
if (!sdout) error("open failed");

// append 100 lines to the file
for (uint8_t j = 0; j < 100; j++) {
// use int() so byte will print as decimal number
sdout << "line " << int(j) << " of pass " << int(i);
sdout << " millis = " << millis() << endl;
}
// close the stream
sdout.close();

if (!sdout) error("append data failed");

// output progress indicator
if (i % 25 == 0) cout << endl;
cout << '.';
}
cout << endl << "Done" << endl;
}
//------------------------------------------------------------------------------
void loop() {}[/code]

I noticed that in the code it mentioned to install a special library (SdFatV2Demo20110108). I downloaded this library from "http://code.google.com/p/beta-lib/downloads/detail?name=SdFatV2Demo20110108.zip&can=4&q=".

With only the new sketch containing the code from the wiki, I select "Verify/Compile" and receive the following errors:

SDCard_DFRobot:11: error: 'SdFat' does not name a type
SDCard_DFRobot:14: error: 'ArduinoOutStream' does not name a type

Starting out...I figured that I probably don't have the library properly installed. How do I properly "install" the library? How do I make sure that the code is seeing this library? I assumed that a simple #include would do the trick, but the following variations didn't work:

#include <SdFat.h>
#include <SdFat/SdFat.h>
#include "SdFat/SdFat.h"

I seems to me that since the SdFat.h file has a SdFat class, there shouldn't be a reason for SdFat to not be a valid type.

I have the sketch (.ino) file in the same directory as the directory containing the SdFat.h file. That is why I chose the SdFat/SdFat.h option.

I clearly am doing something wrong, does anyone have any clues how to help or pointers on methods to try?
