In unix, you may read/write from /dev files. (I'm not sure)

In Windows, I think you need to read/write disk sectors via JNI(Java Native Interface). Calls some C library to talk to the OS.

update: In C library, you may need to use Win32API to get the file handle for example CreateFile(..) function.
