Interesting....I dont believe it is dying, the laptop is not a year old and 
the drive worked perfectly with MS Windows XP just last week.  Neither can it 
be a badly burnt or damaged disk, since the drive is empty.  Personally I am 
leaning toward a configuration file/setting of some sort.  I noticed on this 
last bootup that the error began at the hardware abstraction layer hald.  I 
am wondering if something is telling LINUX to try to read the drive despite 
the fact that nothing is in it.  I am at a loss to know where to begin 
looking for such a file.  Having said all of this you did confirm that it was 
as issue involving the CD/DVD drive--which brings me a quarter step closer to 
a solution.
