i'mI'm new about arduinoto Arduino and electronics. iI want to make a project including sd datalogger.SD data-logger, but iI had a problem. i'am appreciatedI would appreciate if someone show me where i didI made a mistake.

firstlyFirstly, circuit was set up as in picture http://i.hizliresim.com/1kQJDB.jpg i:

Hardware setup

I am using 8gb8 Gb micro SDHC card with SD adaptoradapter. I formatted in FAT32. I can play audio files which are in appropriate format and read and the print contents of text files. but

But when iI want to create a new file, strange file is obtained in SD card as in pic http://i.hizliresim.com/vL1j6O.jpg .:

Directory listing

So I reformat SD card. the code that is used while creating file is as this;

// open a new file and immediately close it: Serial.println("Creating example.txt..."); myFile = SD.open("example.txt", FILE_WRITE); myFile.close();

// open a new file and immediately close it:
Serial.println("Creating example.txt...");
myFile = SD.open("example.txt", FILE_WRITE);
myFile.close();

somewhereSomewhere I read SDHC card with more than 2 gbGb capacity is not supported in aurduinoArduino and I bought 2 gbGb SD micro with SD adaptor. but

But in this case aurduino does not detect SD card. please someone help me.
