the combo drive you listed above is a cd-rw/ DVD-ROM....meaning that it will play and burn cd, cd-r, and cd-rw disks. the dvd rom will only be able to play dvd-rom and dvd-r disks providing they are in the proper format. check that the disk in question is not a dvd-rw or (+2) disk. the drive will not recognize that a disk is in the drive if the disk isnt compatable. try a dvd movie, if that works then a dvd-r, if that works then try a dvd-rw +1. if the last option doesnt work then you will have to stick with the dvd-rom and dvd-r, or purchase a dvd-rw drive to install.
The problem with sony dvd rom is that it reads only original high quality dvd's.if you have purchased any locally avilable cheap dvd,please make sure you don't put it inside ur dvd rom.MAKE SURE U PURCHASE BRANDED DVD'S LIKE SONY,MOSERBAER(ORIGINAL),HP........
do you have software/program that supports DVD.
Try a different DVD/Movie/Disk or alternative.
Also install a program, such as Nero which will give you physical characteristics of the drive.
Finally go to device manager, and remove or uninstall the device, reboot the computer and setup again. This can sometimes remedy the problem.
ensure that the drive is set as Master/Slave. if on the same Bus/IDE channel as a hard-drive. set as master/slave opposite to what the hard-drive is setup as.
Hope this helps.

first you'll need to find out if it's the lens adjustment or a laser problem. this will require you to open up the drive, and test it running open, use protective glasses to shield your eyes from the laser.
buying a new one is faster less time consuming and about 20 dollars. Removing it and connecting the new one, anyone can do 4 screws, and to diff cable that only fit one way.
