    when i go to the current control set class, then to the other file with all the long numbers and letters, it says the data for default as "value not set". When it should say DVD/CD ROM. What should I do??

  • rama2009 Feb 16, 2009

    Hi!



    Last week I was unable to use my DVD drive as it had stopped functioning. On inspection an ACER service recommended a replacement. Even after installing a new one, I am unable to write or read DVD using my DVD drive. My model is Acer Asprire 4520 Laptop, running XP SP-3, 3 Gb RAM ( 1Gb Acer, 2Gb Transcend), 160 Gb HDD.



    Would highly appreciate any advice or a suitable solution.



    Thanks in advance

    I have the same stupid problem.. i have tried everything.. formating hardisk, installing fresh windows.. tried to update chipset.. but it seems nothing works. I read about deleting upper & lowerfilter in Registry editor, but mine doesnt have any upper or lower filter!

    I'm so lost.. i guess I have to forget about using my CD/DVD driver.. **** ACER!

Hi, the error code that you have is a known issue from Microsoft that needs a registry tweaks. Error code means "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (code 39)" . You can click on this link for your reference http://support.microsoft.com/kb/929461/en-us

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_MACHINESYSTEMCurrentControlSetControlClass{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.


This will surely help you resolve your issue. Good Luck!!!
Thanks

Use the net to download driver. Then you can try using your drive. Otherwise your drive may have gone defective itself not allowing windows to see it.

Acer aspire 5102 with philips sdvd8821 dvdram drive


alright. bubul78, your post is in no way shape or form a solution for the problems given by other users. I too have a acer laptop with the philips dvd drive in it, device manager detects the dvd reader and says it is running with no problems. i can hear the drive read the cd when inserted, tho when trying to access the drive through my computer the window hangs at the hourglass for a min or so, then says please insert a cd. only solution is that something is physically wrong with the drive. ok so solution found, replace the cd drive. but where is acers sight to order replacement parts? poor site navigation in my opinion.
