SD care interface with LPC2148 on Development

Hi,

I am trying to integrate SDcard on to my project. My basic Aim is to transfer files to SDcard. The files are nearly 5MB to 10 MB in size. I used NSK electronics LPC 2148 development board. There are some sample SD card programs given.
I compiled the code. The SD card initialization was unsuccessful. The sd_initinialize() function has two conditions : sd_init() and sd_state() is returning is returning a negative value, which means that the SD card is not initialized.

The LCD shows "SD CARD - not OK"
I crossed checked the PIN configuration and spisend() function check, but i still couldn't figure what is wrong ?

Source code for main.c

#include <LPC214X.H>
#include "lcd.h"
#include "type.h"
#include "types.h"
#include "lpc2000_spi.h"
//#include "ssp.h"

//void delay(unsigned long int count1);
void wait (void);
U8 init_sdcard(void);

int main (void)
{
  unsigned char i;
  unsigned status;
  unsigned char SDCheckFlag;

  lcd_init();                                                                                     {
        lcd_write_control(0x01);
        goto_cursor(0x00);
        if(init_sdcard())
        {
        lcd_print("SD card - OK");
                SDCheckFlag = 1;
        }
        //else if(init_sdcard() == -1)
        //{
        // lcd_print("SD Card-error = -1");
        //}
        //else if(init_sdcard() == -2)
        //{
        //  lcd_print("SD Card-error = -2");
        //}
        else
        {
        lcd_print("SD card - not OK");
                SDCheckFlag = 0;
        }

    delay(100000);

  }

}
