  • Hi,

     

    I suggest trying the following methods to troubleshoot the issue.

     

    Method 1 If you have any third-party CD/DVD-burning software such as Naro or Roxio installed, please temporarily remove them from "Control Panel"-> "Programs and Features".

     

    Method 2 Delete Filter Drivers

    ======================

    1. Click Start, type regedit and press ENTER.

    2. Navigate to the following key:

     

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

     

    3. Right click the {4D36E965-E325-11CE-BFC1-08002BE10318} entry, choose "Export", select Desktop in the Save in box and type backup in File Name. Click Save.

     

    Please Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file.

     

    4. Highlight this key ({4D36E965-E325-11CE-BFC1-08002BE10318}), on the right pane, and then check if Upperfilters and Lowerfilters value are present. If so, please right click on the values and select "Delete" to remove them.

    5. Restart the computer.

     

    Method 3 Reinstall the DVD Drive

    =======================

    1. Click Start, type devmgmt.msc and press Enter.

    2. Expand DVD/CD-ROM drives.

    3. Right-click the DVD drive and click Uninstall.

    4. Restart the computer.

     

    If the issue persists, I suggest contacting Sony for more information.

     

    Hope it helps.

  • Hi,

     

    A filter driver is a Microsoft Windows driver that adds value to peripheral devices or supports a specialized device in the personal computer. It is driver/program/module that is inserted into the existing driver stack to perform some specific function. A filter driver should not affect the normal working of the existing driver stack in any major way. Written either by Microsoft or the vendor of the hardware, any number of filter drivers can be added to Windows. Upper level filter drivers sit above the primary driver for the device (the function driver), while lower level filter drivers sit below the function driver and above the bus driver.

     

    Filters may work on a certain brand of device such as a mouse or keyboard, or they may perform some operation on a class of devices, such as any mouse or any keyboard. Another type of filter driver is the bus filter driver, which may be added on top of the bus driver. For example, an ACPI bus filter is added to support power management for each device.

     

    However, a filter driver can cause CD/DVD drive issues. As they are not important files, you can safely delete them if your CD/DVD drive does not work.

  • I also have a VGN-N320E. I tried these steps and the drive now shows, but does not read or write any dvds. It's like a ghost.

  • Dear Tim Quan, I have MATSHITA uj 850s dvd drive. When I connect it to my windows10 tablet, I can see a dvd icon in windows explorer. But when I put any dvd, either blank or movie, it can not read. I have tried to connect the uj 850s to a windows7 laptop. It works perfectly. I have search for a windows10 compatible driver for it ovr the internet, but could not find any. I have tried your solution for windows vista regarding this problem issues, but I can not find upper filter nor lower filter value. Pls do me a favour. Thanks.
