请问在WIN9X/NT下如何写扇区，写者有分

使用DeviceIoControl，具体的可以在MSDN中找到。
BOOL DeviceIoControl(
HANDLE hDevice, // handle to device of interest
DWORD dwIoControlCode, // control code of operation to perform
LPVOID lpInBuffer, // pointer to buffer to supply input data
DWORD nInBufferSize, // size, in bytes, of input buffer
LPVOID lpOutBuffer, // pointer to buffer to receive output data
DWORD nOutBufferSize, // size, in bytes, of output buffer
LPDWORD lpBytesReturned, // pointer to variable to receive byte count
LPOVERLAPPED lpOverlapped // pointer to structure for asynchronous operation
);

在WIN 9X下直接调INT 13H就可以了，在NT下就只有DeviceIoControl了
