STM32F2XX + SDIO + FatFs problem

Hi,

I've a problem with my STM32. I need to use fat filesystem on SD card to read/write/create files.
I tried to use Chan FatFs module but it didn't working at all ...
I use SD card in SDIO and 4 wires mode.
When I debug, check_fs() function can't retrieve 0x55 0xAA on boot sector, but, when I read sector n°0 in the main(), I can correctly read all datas on boot sector.

If someone can help me with this problem ...
Thanks.
