How can I use _FS_NOFSINFO ?

[bianchi77]

Hello Guys,

I tried to read a free space on FAT32 SDcard, based on :
http://elm-chan.org/fsw/ff/en/getfree.html

How can I use _FS_NOFSINFO ?
Because the size I got on UART was not right :
FREE SPACE ON SDCARD
Free space : 692517509 bytes Total space : 199 bytes

My SDCard is 1Gb and is being used about 30Mb

thanks

/* Get volume information and free clusters of drive 1 */
	res = f_getfree("1:", &fre_clust, &fs);
	//if (res) die(res);

	/* Get total sectors and free sectors */
	tot_sect = (fs->n_fatent - 2) * fs->csize;
	fre_sect = fre_clust * fs->csize;

	/* Print the free space (assuming 512 bytes/sector) */
	printf("%10lu KiB total drive space.\n%10lu KiB available.\n",
	tot_sect / 2, fre_sect / 2);
	sprintf_P( &temp_buffer, PSTR(" Free space : %10lu bytes "), fre_sect  );
	usart_pstr( &temp_buffer );
	sprintf_P( &temp_buffer, PSTR(" Total space : %10lu bytes "), tot_sect  );
	usart_pstr( &temp_buffer );
