MicroSD Card Sheild Backward Compatibility

hello forums,

i pretty new arduino programming, , have worked on several small projects before, first project have done involving writing sensor data sd card microsd card shield. 

anyway, problem have have uno r2, , when searching online microsd card shield record data accidentally bought 1 pin configuration uno r3 (i.e., new 4 pins , other slight changes).  bought stackable pin headers configured r3.

since these not fit properly, tried connecting between shield , board:
pin 8 cs/ss (recommended manufacturer opposed 4)
pin 11 mosi
pin 12 miso
pin 13 clk/sck
with jumper wires.

however, microsd card failed initialize when when used manufacturer's test code (below).

is there correct way wire microsd card shield arduino uno r2, , if not, suggest?  appreciated, , sorry if appears bit of newbie question.

code: [select]


// include sd library:
#include <spi.h>
#include <sd.h>

// set variables using sd utility library functions:
sd2card card;
sdvolume volume;
sdfile root;

// sparkfun microsd shield uses pin 8 cs
const int chipselect = 8;

void setup()
{
  // open serial communications , wait port open:
  serial.begin(9600);
  while (!serial) {
    ; // wait serial port connect. needed leonardo only
  }


  serial.print("\ninitializing sd card...");

  // note if it's not used cs pin, hardware ss pin
  // (10 on arduino boards, 53 on mega) must left output
  // or sd library functions not work.

  pinmode(10, output);


  // we'll use initialization code utility libraries
  // since we're testing if card working!
  if (!card.init(spi_half_speed, chipselect)) {
    serial.println("initialization failed. things check:");
    serial.println("* card inserted?");
    serial.println("* wiring correct?");
    serial.println("* did change chipselect pin match shield or module?");
    return;
  } else {
    serial.println("wiring correct , card present.");
  }

  // print type of card
  serial.print("\ncard type: ");
  switch (card.type()) {
    case sd_card_type_sd1:
      serial.println("sd1");
      break;
    case sd_card_type_sd2:
      serial.println("sd2");
      break;
    case sd_card_type_sdhc:
      serial.println("sdhc");
      break;
    default:
      serial.println("unknown");
  }

  // try open 'volume'/'partition' - should fat16 or fat32
  if (!volume.init(card)) {
    serial.println("could not find fat16/fat32 partition.\nmake sure you've formatted card");
    return;
  }


  // print type , size of first fat-type volume
  uint32_t volumesize;
  serial.print("\nvolume type fat");
  serial.println(volume.fattype(), dec);
  serial.println();

  volumesize = volume.blockspercluster();    // clusters collections of blocks
  volumesize *= volume.clustercount();       // we'll have lot of clusters
  volumesize *= 512;                            // sd card blocks 512 bytes
  serial.print("volume size (bytes): ");
  serial.println(volumesize);
  serial.print("volume size (kbytes): ");
  volumesize /= 1024;
  serial.println(volumesize);
  serial.print("volume size (mbytes): ");
  volumesize /= 1024;
  serial.println(volumesize);


  serial.println("\nfiles found on card (name, date , size in bytes): ");
  root.openroot(volume);

  // list files in card date , size
  root.ls(ls_r | ls_date | ls_size);
}


void loop(void) {

}


how did wire power , ground? sd shield use 5v or 3.3v?
