Hi,
Drive or cable could have an issue.
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 your 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.

You probably can find more info here and maybe even the exact registry settings for your CD/DVD
drive from someone with the same model.

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.
DevManView - Free - an alternative to the standard Device Manager of Windows, which displays all
devices and their properties in flat table, instead of tree viewer
