Cdrw/dvdrw won't recognize or read cd. I replace original cdrom and it works fine. Worked when first installed?!?!


Answers :

Since you've already replaced the cdrom, the next thing you need to do is delete this registry files,..
\015\012
\015\012This fix came from microsoft if your optical drive can't read or recognize discs,.
\015\012
\015\012if your using windows vista or windows 7, click on the start button then in the start search box type in REGEDIT,
\015\012
\015\012If your using windows xp click on the run icon then
\015\012type REGEDIT.
\015\012
\015\012
\015\012After that look for this,
\015\012
\015\012HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Class\\{4D36E965-E325-11CE-BFC1-08002BE10318}
\015\012
\015\012There 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.
\015\012In the right pane, right-click UpperFilters, and then click Delete.
Click Yes to confirm the removal of the UpperFilters registry entry.
In the right pane, right-click LowerFilters, and then click Delete.
Click Yes to confirm the removal of the LowerFilters registry entry.
\015\012Then after that go to device manager, look for your cdrom device, you can easily find it,.
\015\012
\015\012If your using windows vista or seven just right click
\015\012on the computer icon then properties,
\015\012then on the top right corner of the window you will see device manager, click it, then look for the
\015\012cdrom, click the cdrom icon, a drop down box will come up, click on the item that came up, then right click it, click on uninstall,
\015\012
\015\012Do the same thing in xp, but to get to device manager right click on my computer, then do the same process.
\015\012
\015\012after that restart the computer and it will automatically restart.
\015\012
\015\012If this one still doesn't work, update the firmware of your
\015\012cd rom which you can get from dell's support website, after that if all else fails,
\015\012back all your files and then reinstall the operating system.
\015\012
\015\012Hope this helps!
