The following C++ example shows how to align sectors for unbuffered file writes. The Size variable is the size of the original data block you are interested in writing to the file. #include <windows.h> #define ROUND_UP_SIZE(Value,Pow2) ((SIZE_T) ((((ULONG)(Value)) + (Pow2) - 1) & (~(((LONG)(Pow2)) - 1)))) #define ROUND_UP_PTR(Ptr,Pow2)  ((void *) ((((ULONG_PTR)(Ptr)) + (Pow2) - 1) & (~(((LONG_PTR)(Pow2)) - 1)))) void main() { // Function code     DWORD BytesPerSector = 0; // obtained from the GetFreeDiskSpace function.     DWORD Size = 0; // buffer size of your data to write // ... obtain data here // sample data     BytesPerSector = 65536;     Size = 15536; //    // Ensure you have one more sector than Size would require.    SIZE_T SizeNeeded = BytesPerSector + ROUND_UP_SIZE(Size, BytesPerSector);      // Replace this statement with any allocation routine....
