Is there a way to check if a CD-R is finalized in Java?

I am writing a program, and one of the requirements is that data can only be accepted from a CD-R that has been finalized. I cannot for the life of me figure out how to accomplish this check in Java. Any help would be much appreciated!

When a CD is finalized, it reports zero free file space.

Since Java 1.6, the File class has a getFreeSpace method.

When I tried this code on my Windows C: drive, it returned 403,547,947,008.

package com.ggl.testing;

import java.io.File;

public class GetFreeSpace {

    public static void main(String[] args) {
        File file = new File("C:");
        System.out.println(file.getFreeSpace());
    }

}

Try it on your CD drive, and see if it returns zero or a number, for a finalized CD or a not finalized CD, respectively.
