Corrupted DVD driver

[Wallace]

My DVD driver on my Aser Vista laptop has got corrupted so I can't see my
DVD drive. I've tried going in to Safe mode then uninstalling the driver and
then allowing Vista to load the driver up on reboot. But it's still
corrupted. I can't find the right drivers- it's an HL-DT-ST DVDRAM GSA-T10N
ATA device. Not sure of the manufacturer but may be Hitachi.

Also I've tried System Restore and that just states that it didn't work.

Any suggestions?

Click Start,type 'System' in the search box. When System Information
comes up, double click on it. Click on the + in front of Components,
locate either CD-ROM or DVD then in the right window pane check to be
sure it is the right device if you have optical devices, then at the
bottom locate the name and location of it's driver.

Now go to the folder the driver Vista said the driver is located in,
right click on the file, properties, rename... simply put a X in front
of the name.

This should prevent Windows from finding the old corrupted version at
boot. Now reboot and it should bring up the found new hardware box and
it should ask you to insert the CD with the driver for your device.

Ring Acer, as it is under warranty. With Acer, you won't have the CD to
install just the DVD driver. It will be a complete reinstall, not a partial
install.
One of the quirks of Acer computers.

Try this below. Check you Upper and Lower filters. Applies to Vista also

Your DVD is made by LG. Try contacting them for driver.

Removing the value in the Upper and Lower filter worked.

It was a Freecom driver that removed the DVD access.

Thanks for people's help.

how do i change the value in the upper and lower filter. cos am having
same problem with same model of laptop

You don't change them, you delete them. When you reboot, they are recreated.
You will find them under:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Hi,
I had the same problem, tried the upper and lower filter... it helped, but unfortunately I deleted the filters, not only the values... did I something wrong? does it matter? should I correct something? The DVD driver works now...

Thanks in advance

Wallace and Peter for posting the problem and the fix. Peter the link no longer works but I was able to search and find this. Now my DVD works again. I had up graded to vista on my Acer 5100 and was suprised when it no longer worked

RESOLUTION
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 the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this problem, remove the affected filter drivers. To do this, follow these steps:1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.

If you are prompted for an administrator password or confirmation, type your password, or click Continue.
2. Locate, and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
3. In the right pane, right-click UpperFilters, and then click Delete.
4. Click Yes to confirm the removal of the UpperFilters registry entry.
5. In the right pane, right-click LowerFilters, and then click Delete.
6. Click Yes to confirm the removal of the LowerFilters registry entry.
7. Exit Registry Editor, and then restart the computer.
Note After you remove the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall any affected programs. If the problem recurs, contact the program vendor to determine whether an update is available for the program.

When I open the path in regedit and want to open: properties to change filters, then I get a error:

Can't open properties.
Can't open this key because of a error.
Details: Access denied.

The problem is that there's a error in the opperatingsystem, so they are still in the list of hardware, but all the program's can't find them.

I hope somebody can help me out here.

Sorry for my bad english :)

I just purchased a Toshiba Laptop, running Vista Premium, and after a massive Windows update download, the DVD-CD drive didn't work. Error message 39, corrupt or missing driver. The driver isn't missing, so it must be corrupt. Have followed the above instructions regarding upper and lower filters, except haen't actioned the removal yet, as there doesn't appear to be an upper filter listed... only the lower filter. Also, the information states "you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall any affected programs." which is a problem, as everything was already loaded and no software came with the laptop. I'm a little chicken to go ahead and remove the lower filter registry entry, seeing as there's no upper entry to delete. What do you think I should do???
Thanks in advance folks, Anniebird

The next thing I guess is; how do I get my hands on a copy of the software to reinstall the dvd player so it will record... not just play, but the notebook didn't have any cd's with purchase.

This really is a bit much. I purchased this model (Toshiba Satellite L300, model PSLBOA-08H022) because I want to save large graphic files to DVD discs. Buying a new notebook, I thought I'd be free of problems, but after reading all the google stuff on Toshiba Satellites and Vista, I feel I probably should have researched further before buying! Makes me scared to download anymore Vista updates!

I appreciate the input from all of you. Where would us novices be without you.

To solve this Code 39 error, follow these instructions:

NOTE: After removing these registry keys and rebooting, it may be
necessary to reinstall any CD or DVD recording applications.

1) Close all open programs


2) Click on Start, Run, and type REGEDIT and press Enter

3) Click on the plus signs (+) next to the following folders

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Control
Class
{4D36E965-E325-11CE-BFC1-08002BE10318}
4) This folder is the DVD/CD-ROM Drive Class Description in the
registry. Look for any of the following names in the right hand column.

UpperFilters
LowerFilters
UpperFilters.bak
LowerFilters.bak
5) If any of the above keys shown in step 4 are listed, right-click on
them and choose Delete

6) After deleting the keys, close the Registry Editor

7) Reboot your computer

8) Open My Computer and check to see if your CD or DVD drives have
returned. You may also want to open Device Manager and verify that the
yellow exclamation and error code on the CD or DVD drive is gone.
It worked for me.

Read the following from the Microsoft KB on this error 39 and follow the instructions to the letter.

My DVD is now working and no need to restore computer.

For anyone wanting to try this fix, go to your Windows Help and type in
"Registry Editor" for information on how to find and backup registry
data. Find the correct registry subkey by following step 2 and then
back it up per help instructions. Then follow steps 3-7 given in Don's
resolution. Follow step 2 on this exactly!

I have forwarded this information to Acer support.

what if yo don't have any upper or lower in your Class?

It might the the drive, not Windows. Anyway, does Samsung have the drivers
