I can't seem to figure out why my SD card won't initialize. I checking the voltage and after the SD card is connected the voltage rises from 3.3 to 3.6V and then 500ms later jumps to 3.9V. I'm using the 3.3V pin from the Arduino Duemilanove. Is this normal that the voltage would increase after plugging in the SD card. I don't think the pins I'm using for the SPI connection are incorrect.
