I have a Compaq V4000 that does something similar.  The OS (either Linux 
or Windows) will not recognize the DVD drive unless there is a disk in 
the drive at boot.  I'm not sure if it's a hardware or software issue. 
I've worked around it by simply rebooting whenever I needed to use the 
drive.  Luckily, I don't use the drive all that often...
