I have modified the SD2pinmap.h lines 41 to 45 to this
// SPI port
uint8_t const SS_PIN = 49; // SC 53 or 49???
uint8_t const MOSI_PIN = 52; // data out
uint8_t const MISO_PIN = 50; //data in
uint8_t const SCK_PIN = 51; // CLK
I am trying to get the example SDfatinfo.pde to work, and modified the code from line 148 to 150.
pinMode(53, OUTPUT); // set the SS pin as an output (necessary!)
digitalWrite(53, HIGH); // but turn off the W5100 chip! (not applicable)
uint8_t r = card.init(SPI_HALF_SPEED, 53); // Use digital 53 as the SD SS line
Running the gets this reply in the serial monitor (comments were added manually and are the different cards

Can someone help me pinpoint why I can't read the info of any of the cards?
I have spent an hour looking for furthur documentation on this and have found none.
I spent another hour using my minimal experience looking through the code in the libraries trying to find where the error codes come from and have only found a headache.
Could any of you guys who are more experienced take a look at this as I really am just as frustrated and lost as OP. [smiley=undecided.gif]
Thank you much Richard Crowley. Yet another reason to not debug at 4am. Mine is a 32MB Cannon and threw the same errorcode: 2 that dwjp902 got. Dunno how I missed that, but here it is for Dwjp902.
//32MB Cannon
errorCode: 2 /** CMD8 was not accepted - not a valid SD card*/
errorData: FF
//your card is probably too small or not configured correctly.
//2nd 32MB Cannon
errorCode: 2 /** CMD8 was not accepted - not a valid SD card*/
errorData: FF
//your card is probably too small or not configured correctly.
//128MB Kodak
errorCode: F /** timeout while waiting for start of read data */
errorData: FF
//try doing a FULL FORMAT and maybe increase the value of [uint16_t const SD_READ_TIMEOUT = 300;]
//2BG Kingston MicroSD+adapter
errorCode: E /** read CID or CSD failed */
errorData: FF
//no idea what this means. need to research.
//4GB PNY SHDC microsd+ adapter
errorCode: E /** read CID or CSD failed */
errorData: 1F
//no idea what this means. need to research.
ALSO, I noticed the following in SdCard.h
// define software SPI pins so Mega can use unmodified GPS Shield
/** SPI chip select pin */
uint8_t const SD_CHIP_SELECT_PIN = 10;
/** SPI Master Out Slave In pin */
uint8_t const SPI_MOSI_PIN = 11;
/** SPI Master In Slave Out pin */
uint8_t const SPI_MISO_PIN = 12;
/** SPI Clock pin */
uint8_t const SPI_SCK_PIN = 13;
I suggest you change that to this:
// define software SPI pins so Mega can use unmodified GPS Shield
/** SPI chip select pin */
uint8_t const SD_CHIP_SELECT_PIN = 53;//10; 53 or 49?
/** SPI Master Out Slave In pin */
uint8_t const SPI_MOSI_PIN = 52;//11;
/** SPI Master In Slave Out pin */
uint8_t const SPI_MISO_PIN = 50;//12;
/** SPI Clock pin */
uint8_t const SPI_SCK_PIN = 51;//13;
This isn't the first thread I have seen on this topic either. Usually the thread just dies after a while with no clear resolution. As soon as any of us get that thing working, please share a link to the library for download + how you made it work and/or a modified version of the library for simplicity. Solve this issue once and for all!
I got it to work, I changed the speed value to 1/4
pinMode(53, OUTPUT); // set the SS pin as an output (necessary!)
digitalWrite(53, HIGH); // but turn off the W5100 chip! (not applicable)
uint8_t r = card.init(SPI_QUARTER_SPEED, 53); // Use digital 53 as the SD SS line
and the info returned this
