It's difficult to help you without any further information, but maybe the following thread is helpful to you: STM32 : FatFs Library - f_mount

  • If this does not help you, please give additional information: show your code, which library are you using,... – MemAllox Jan 17 '18 at 19:58
  • I'm using FATFS_V010B, before that this program has been tested by stm32f429 discovery board and it was ok but with my board not ok, i checked the pins 100 times and it was ok and crystal has 8MHZ frequency. the initialize return is SD_OK. – M.kh Jan 18 '18 at 06:52
