Hi, In Windows we can open and read storage meidias by using the call CreateFile() and ReadFile() respecively. The device name is passed as a string to the CreateFile() call, as an example "PhysicalDrive1". Create file returns a handle of type "HANDLE". can I use this handle in asio in order to read a device file?

Yes, take a look at boost::asio::windows::random_access_handle and random_access_handle_service. You can use this in normal calls to async_read, async_write, etc
