Hi Fansteroni and welcome.

Please check in Device Manager to see if there is a Yellow "!" Error message against your DVD/CD-ROM Drive.  If there is an error, please supply the error code.

Also can you check for the correct Vaio model - you will find it on the screen surround.

Hi Fasteroni.

Double-click on the drive in Device Manager - What error code is Device Manager reporting?  If it is code 19, 31, 32, 39 or 41 then a small registry edit should sort the problem.

The following involves changes to the registry and I recommend that you set a System Restore Point.

Then:

1.Press the ‘Windows’ key and press R. In the Run box type: REGEDIT  and hit enter. For Vista/Win7, type REGEDIT into the search box and open it).

2. Navigate to –

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

click on this and locate UpperFilters in the right-hand window, (if it exists) right click on this and select Delete and then OK.

3. Under the same Registry Key locate LowerFilters, (if it exists) right click on this and select Delete and then OK.

4. Quit Registry Editor and re-boot the computer, new registry values will be created that will hopefully cure the problem.

After you remove the Upperfilters value and the Lowerfilters value, you may possibly need to re-install your burning software if it doesn't work – but this is only rarely needed.

Good Luck!

It is just a safeguard in case something gets changed in the Registry by accident.  If you are careful, it is not that important.
