Windows 7: DVD Drive undetected

DVD Drive undetected

I have a Liteon iHaS124 (B version?) and I have kind of a bizarre problem with it. It worked well for over a year, now suddenly I have no detected drive at all.

I tried flashing the FW back to stock, but it says no drive detected. It's definitely connected and powered, I can eject just fine but there is no DVD drive shown under My Computer at all.

I don't see any drivers for this, it seems to be using a default 2006 CD-ROM driver from Microsuck. Dafuq? I thought Windows 7 was newer than 2006 even... If I try to update driver it claims I have the latest driver and there's nothing newer than 2006 -____-

Here's a screenshot from my Device Manager: imgur: the simple image sharer

The yellow exclaimation point is because "windows cannot load the drivers for this device" and the one below it I believe is related to either VMware or another type of Virtual Drive. I disabled it for troubleshooting. If either are uninstalled they just come right back.

Hi Joe

See if this works for you

Click button
Type regedit, and press Enter key.
User Access Control permission
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
In the navigation pane, locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
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.
On the Edit menu, click Delete.
When you are prompted to confirm the deletion, click Yes.
In the right pane, click LowerFilters.

Note If you do not see the LowerFilters registry entry, unfortunately this content cannot help you any further. G
On the Edit menu, click Delete.
When you are prompted to confirm the deletion, click Yes.
Exit Registry Editor.
Restart the computer.

Opened up Properties in "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}" and it says Access is Denied which is odd, I've never seen access denied in regedit. Anyways there are no upper filters only lower, I'll try deleting that.

*edit: I know it doesn't say anything about Properties, was just curious. I followed what it says exactly.

*edit#2: It worked! How did you know about that, and can you give any background on it? Could it be related to a custom firmware or microsoft update?

That fix goes away back to Windows XP days.

It could be how Windows is reading the drivers for the drivers. Or the Burning software. Sometimes when you remove the Upper Filters and the Lower Filters it will require you to reinstall your burning DVD software once more.
