DVDRAM GSA-T20L NOT RESPONDING TO cd

SOURCE: HL-DT-ST DVDRAM GSA-T20L ATA Device

ok you can do two things to fix it

first of all go to start
go to run
type regedit and hit ok
now in the registry go to this path

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

and remove both upper and lower filters from the right pane

now close the registry editor.

reboot the computer and see if that fixed it or not

if not the download the drivers from this website.

just select the operating system that u have and then download it and reinstall the driver and then reboot the computer

that should be it

if still not working then i guess its a hardware issue

cheers

This is a common problem try this: Windows XP

1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. In the navigation pane, locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
4. In the right pane, click UpperFilters.
   
   Note You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 7.
5. On the Edit menu, click Delete.
6. When you are prompted to confirm the deletion, click Yes.
7. In the right pane, click LowerFilters.
   
   Note If you do not see the LowerFilters registry entry, unfortunately this content cannot help you any further. Go to the "Next Steps" section for information about how you can find more solutions or more help on the Microsoft Web site.
8. On the Edit menu, click Delete.
9. When you are prompted to confirm the deletion, click Yes.
10. Exit Registry Editor.
11. Restart the computer.
