"Ghost" CD-drive in Windows Explorer, no physical drive attached

For some reason, I have a phantom F:\ drive. The phantom drive thinks it's a CD player, but it's not. There's no hardware there.

No, it's not a virtual drive either.

Look below. Notice how the F:\ doesn't show up in my Disc Management? But yet, Windows Explorer totally thinks it's there. It doesn't show up in my Device Manager either. (FYI, typically my F: and G: drives are for external HDDs - which I don't have turned on right now. If I turn the one that's typically Drive F on, it gets assigned as Drive G.)



Doesn't show up in the registry either.



My drive paths should be as follows:

D: internal CD-ROM
E: internal CD Burner
F: (typically external HDD)
G: (typically external HDD)
H: External Compact Flash Reader
I: External Memory Stick Duo Drive
J: External Memory Stick Drive
K: USB PSP Connection (only when plugged in)
L: Unassigned
M: External DVD Burner
N-U: Unassigned
V: Virtual Drive (when in use - currently set to 0 Virtual Drives)
X-Z: Unassigned

So far, I've figured out that it's a clone of my DVD Burner.



If I select F:\ and click the eject button, my DVD Burner opens up. If I select M:\ and click the eject button, it does the same thing.

I don't know what caused it or how to get rid of it. How do I make it so that only the M: drive recognizes my DVD Burner?

I searched the threads and found that this guy had the same problem - and he seemed to have figured it out, but I couldn't understand what he did to fix it.

Please help.

 

Oh think I get it, so he manually turned the feature on in PowerDVD, and then set it to zero and turned the feature back off, right?

Incidentally, what would be the purpose of PowerDVD creating a ghost drive? Is it just a glitch?

Thanks.
