Like I said I haven't spent any time on the F1 code, my boards aren't using them.

uint8_t SD_Detect(void)
{
__IO uint8_t status = SD_PRESENT;
/*!< Check GPIO to detect SD */
if (GPIO_ReadInputDataBit(SD_DETECT_GPIO_PORT, SD_DETECT_PIN) != Bit_RESET)
{
status = SD_NOT_PRESENT;
}
return status;
}
Reading the larger cards has the potential to return the wrong data, writing has the potential to trash the file system.
