I use fatfs as file system and use sdio_sdcard.c as sd card driver write data into sd card
but i found a problem when i use SD_ReadMultiBlocks function sometimes there will some sectors didnt fill the data, there are some my deleted file data in it(if i format all sd card it will be all 0x00),the sector always occur at 0xXXXXXe00 and end with 0xXXXXXX00 which means there is whole 512 bytes sector fail

what makes this problem? when i try simplest program which just fill same data into a file and stop all interrupts and any another function
the problem still occur, please someone help
