I am using a laptop that is a HP Pavilion dv4 Notebook PC.

The OS being used is the 64-bit Windows 7 Home Premium.

Any time I insert a data CD-R into the DVD RW Drive, it is always identified as a blank CD-R.

 

Please help me fix this problem!

Run this Microsoft FixIt troubleshooter to see if that resolves the problem.

I have done as your instruction. But it does not fix the problem at all. 

When I ran the troubleshooter, I got the notice as follows:

"Troubleshooting is complete - We detected some problems with your system and were able to successfully  apply the fixes. However, our verification shows that the problem still exists. Issues found - Media in CD-DVD drive is not readable (hp DVDRAM GT30L). Status: Not fixed"

Please follow this procedure:

 

  1. Press the Windows logo key + R to open the Run dialog box.
  2. Type regedit in the Run dialog box, then press Enter. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow
  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, go to step 10.
  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.

Please let us know if this fixes the problem.

I see neither UpperFilters nor LowerFilters in 

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

in the Registry Editor.

 

Obviously, your procedure does not still fix the problem.

Is my DVD RW Drive out of order? 

Is it time for me to replace it with a new one?

Reinstall the drivers for the drive as below:

 

  1. Press the Windows logo key + R to open the Run dialog box.
  2. Type devmgmt.msc in the Run dialog box, then press Enter. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow
  3. In Device Manager, expand DVD/CD-ROM drives, right-click the DVD-RW device, and then click Uninstall.
  4. When you are prompted to confirm that you want to remove the device, click OK.
  5. Restart the computer.

After the computer restarts, the drivers will be automatically installed.

 

If this does not resolve the problem, check that the lens in the drive is not dirty.  You may need to obtain a cd/dvd drive cleaning disc to do this.

In Window Explorer, under Devices with Removable Storage, I right click DVD RW Drive (F:), point to Properties, click Hardware tab, I see Device Properties as follows:

 

Device status: This device is working properly.

We are trying to eliminate possible causes of the problem.  Reinstalling the device will ensure that all the correct drivers are present and registry entries in place.

Following your instructions, I have done the following:

  • Reinstall the driver of DVD RW Drive
  • Clean the lens in the drive using a cotton rod soaked in the solution of alcohol 

 

PROBLEM SOLVED!

Frankly, I am very sorry for this inconvenience. But the problem has returned.

Although I have cleaned the lens in the drive many times, the problem has still existed.

Actually, I do not know why this is.

I do not know any way to fix it.

I have found out an interesting phenomenon that is that when I insert a data dvd disc into the drive, it works properly as usual. But when inserting a data CD disc,  it is always identified as a blank disc.

 

How should I edit the values in registry to fix this problem successfully?

It could be that the drive is having hardware problems. If memory serves, optical drives use different lenses/lasers for DVDs vs CDs, so maybe the CDs lens/laser is failing/failed.

I feel for you, you have run the gambit!  IMO $25-30 and 20 minutes of your labor at this point is the best route.
