Hi clive,Does mean I need to leverage by block?for example://assume 1 block = 512 byte HAL_SD_WriteBlocks(&hsd2, aTxBuffer, 0, 1,2000); // = write aTxBuffer into number block 0 (address 0x00000000) by 1 block HAL_SD_WriteBlocks(&hsd2, aTxBuffer, 1, ...

I resolved the issue by decrease clock rate from 50M to 20M.//peripheral 200MFrom hsd2.Init.ClockDiv = 2;to hsd2.Init.ClockDiv = 5;
