Hey, My SD Card Module is not working???!!!

Hi, I am now struggling with 'SD-card module'.
I thought that if I correctly plug lines in:
SD // Arduino
GND - GND
Vcc - 5V
MISO - 12
MOSI - 11
SCK - 13
CS - 4
//////////////
It should work!

However, when I uploaded 'Card Info' sketch, it said 'Initialization Failed!'

So... If I am getting everything right,
including Wire connections, Code(from the examples), and Plugged my '2GB' micro-SD card in,

Why would this happen???

Do you think there is something I am missing????

Please help! I would really appreciate it!

Very likely.
Has the card been properly formatted?

Does your 'SD-card module' include a 3.3V regulator and 5V to 3.3V signal level converters?

Card formatting - be sure to use the one here

Ciao,

Try Pin(10) for CS as it is hardware SS pin on most arduinos and Pin(53) on mega.
