The problem is solved after all: Windows 10 is unable to format SD card with Fat32 properly. I've got it wired to the mega pins 50-53 (these are the default SPI pins on the mega 2560 53 is ss so CS from the SD reader is there now) so its ok if it doesn't release it nothing else it going to use it. Also the input pins of the SD can't handle 5Volt signals. The SD card reader pinout essentially refers to the connections used to interface with an SD card – a widely used data storage medium that offers high capacity and reliable performance. I tried the program with an Arduino Uno with both SD module but nothing occurs on the serial monitor even the Initializing SD card message.
