Satellite L505 Not Recognizing Disks

I am using Windows 7 and my computer is unable to recognize anything I put into the Dvd drive.  When I insert a disk (which is recognized by other computers) nothing shows up in "My Computer" and the drive makes noises as if something is moving back and forth and never "spins" up like any other computer will.
