Problem to read SD cards?

I have problem to get info about my SD card connected to Arduino Leonardo. I use following SD card and SD card holder for Arduino Leonardo, look at attached picture. I have used the code below the text and tried to change const int chipSelect = 4 to value 8 and 10 and also checked all connections and they are correct. But still it doesn’t recognize the SD card.

Can I have damaged my SD card holder because I used at misstake 5V? Does CLK mean the same as
SCK?

The circuit:
 * SD card attached to SPI bus as follows:
** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
** CS - depends on your SD card shield or module.

The SPI pins on the Leonardo:

SPI: on the ICSP header. These pins support SPI communication using the SPI library.
Note that the SPI pins are not connected to any of the digital I/O pins as they are on the Uno, They are only available on the ICSP connector.
This means that if you have a shield that uses SPI, but does NOT have a 6-pin ICSP connector that connects to the Leonardo's 6-pin ICSP header,
the shield will not work.

Did you connect to the ICSP?

Ken76:
Can I have damaged my SD card holder because I used at misstake 5V?

The 3.3V is probably an output, it looks like the shield is run with 5V.
So if you did not connect the 3.3V to 5V...

i have same problem with leonardo. i am using SD card shield (see attached photo) so there is no way that wiring is wrong. i tried cardinfo example and also SDFat library but the card cant be initialized

Hello

I have been searching for almost three days for an answer for my issue and did not get any and it is as following :

I have arduino Leonardo + Seedstudio SD card shield V4.3 (http://wiki.seeed.cc/SD_Card_shield_V4.0/)

and i tried both codes mentioned in the wiki but none of them worked

/*
      SD card test

     This example shows how use the utility libraries on which the'
     SD library is based in order to get info about your SD card.
     Very useful for testing a card when you're not sure whether its working or not.

     The circuit:
        SD card attached to SPI bus as follows:
     ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
     ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
     ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
     ** CS - depends on your SD card shield or module.

I tried both SD and SDFat libraries CardInfo examples and none worked, after searching alot, some mentioned that on Leonardo we should set pin10 to HIGH and i did it and still not working…

I have tested two SD cards : SanDisk Ultra (16GB, micro SDHC, FAT32 format) and Joyflash (4GB, micro SDHC, FAT32 format) and both could not be initialized…

i found also somewhere this code which looks cool but same problem

#include <SD.h>
#include<SPI.h>

void setup() {
  Serial.begin(9600);
  while (!Serial);

  pinMode(10, OUTPUT);
  digitalWrite(10, HIGH);

  Serial.print("Starting SD...");
  if (!SD.begin(4)) Serial.println("failed");
  else Serial.println("ok");
}

void loop() {
}

any ideas please before i get mad :frowning:
