Copy Protection first requires you to detect bad sectors in the floppy disks.  Then four of the bad sectors must be selected.  Then pressing the copy protect button will write a secret data to the floppy disk which is the key disk.
Then for using the copy protected floppy disk you have to call the DLL file which reads the secret area and determines if it is the copy protected key floppy disk.  The DLL can be called anywhere in your program, even in Visual Basic.
