Stage 1 : Please do all the below even if you have done some before as it is often the total
process which solves the issue.
Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab -
click Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL -
REBOOT this will refresh the default driver stack. Even if drive is not shown continue
below.
Then work your way through these - remember the drive could be bad, could have a loose
cable or slight corrosion on the contacts (usually for a laptop) and other issues.

Another possibility is that the cables are loose. Remove ALL power, then check cables in both
ends. Remove and replace, do not just snug. For laptops you can often clean the power and
data contacts with a pencil eraser.
Some DVD drives do not use the Windows default drivers so check with the System maker and
device maker to see if there is firmware or drivers for you drive if needed.
Stage 2 : You could have drive issues as the CD/DVD is actually 4 drives in 1 case ( CD & DVD
burn and CD and DVD read). So it is not unusual for 1 or 2 parts to not function while the others
do so properly.
Did you complete the troubleshooter for the drive that still does not work? There are some
registry entries that the troubleshooter does not fix and those 'might' be the cause.
Check with your System Maker and Device maker for both possible firmware updates and the
correct Registry entries for your drive.
These are the keys I think are the ones in question - for the CD/DVD drive sub-keys of course
as there will other sub-keys in these keys. Be sure to ask for specific keys involved as well as
the settings.

Use DevManView to locate CD/DVD in registry (be careful and make a Restore Point before
changing anything) - find the device in DevManView and then Right Click on it Open in RegEdit.

Plextor PX-B940SA
Blu-ray burners are advancing at a fast pace: Only a couple of months ago I was marveling at the speed of 8X Blu-ray burners--now here I am again with the 12X Plextor PX-B940SA ($250, price as of March 5, 2010). The write speeds make this Blu-ray drive an especially appealing option.
Even though 12X-rated media isn't available yet, judging from my tests the drive will hit 10X write speeds with 4X-rated media, and 12X speeds with 6X media (Panasonic and Sony currently sell 6X-rated media). The drive maxes out at 12X write speeds, but like most 4X or greater drives, it starts slower and gradually ramps up.
Writing 23GB to a single-layer 4X-rated BD-R disc at 10X with the PX-B940SA took about 11 minutes, 31 seconds (or about 7.4X), and burning 40GB to a dual-layer 2X disc took 22 minutes, 19 seconds (or about 6.6X). With 6X media, write speed improved to 7.8X. By way of comparison, the 8X-rated Pioneer BDR-203 averaged around 6X with 4X-rated BD-R.
Since Blu-ray rewrite technology is still stuck at 2X (9MB per second), backing up to BD-RE is still a somewhat time-consuming process. The unit's other speeds are 16X for writing and reading DVD+R/-R, 8X for DVD+RW, 6X for DVD-RW, 8X for DVD+/-R dual-layer, and 5X for DVD-RAM, as well as 40X with CD-R and 24X with CD-RW.
Plextor bundles CyberLink's BD Suite to take care of burning, movie authoring, video playback, and other tasks. The software is more than capable, but it also bugs you incessantly with registration notices and ads--far more than appropriate for software that the user ostensibly paid for. The program offers no option to bypass the registration, but it does give you a way to disable push advertising; even so, some annoying ads remain in PowerDVD and other modules.

CyberLink and Plextor both tout the PowerDVD 8.0.3223 playback software's TrueTheatre feature for enhancing 480p DVD video to 1080p-like quality. In my trials, it seemed to create a sharper picture than VLC, but the results were not on the level of 1080p; you sacrifice GPU assistance to use the feature, too. PowerProducer 5.0.2.2013 and PowerDirector 7.0.0.3227 are on hand for capturing and manipulating video and images for CD/DVD/AVCHD/Blu-ray movie discs, and LabelPrint 2.5.2130 is available for creating labels and jewel-case inserts. PowerBackup 2.50.5187 is installed to deal with backup chores.
Power2Go 6.1.0.3401 is included for handling some of the more pedestrian data tasks. It also rips audio CDs, converts audio between WMA and .wav, saves nonprotected DVD-movie structures to disc, and creates and burns images (in CyberLink's .p2i format as well as standard .iso).
The Plextor PX-B940SA is a great drive that suffered nary a hiccup in my testing. It's faster than anything you'll currently find on the market.
