DVD-RAM driver will not install

[Polojoe]

The DVD - RAM/CD rom driver will suddenly not install on my VGN-SZ4. So I can not use the DVD drive.
Could someone please help how to fix/find or reinstall the orginal driver? I do not seem to find it under C:/drivers?

Hi Polojoe,

Most of the drivers are part of the Windows operating system - there is no special driver.

Do you have an error code showing in Device Manager against the drive?

Thanks for your quick reply!

It was code 32. Some googling showed that many had the same problems after vista updates. It was sorted by going into regedit and resetting the lower and higher filters. Now it is finally working fine again.

Hi Polojoe,

There is a fix that should help Microsoft , see below..

It would be wise to back up your registry first, here is a GUIDE

Manual steps to delete the UpperFilters and LowerFilters registry values that can cause CD access problems
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To manually delete the UpperFilters and LowerFilters registry values, follow these steps:
1.Start Registry Editor (Regedt32.exe).
2.Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
3.On the Edit menu, click Delete, and then click OK.
4.Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5.On the Edit menu, click Delete, and then click OK.
6.Quit Registry Editor.
NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.

7.Restart your computer.
