Please Help: Windows Problem?

This thread is about the LG GGW-H20L. Click here to see full specs

I have a LG GGW-H20L DVD/Blue Ray burner which I recently installed in a Vantec external enclosure. My goal was to move it between systems; A desktop running XP Pro, A desktop running Vista/Win 7 in dual boot, and a laptop running WinXP Media Edition. The portable drive burns all CDs and DVDs fine on the desktops but as far as the laptop goes it burns some but not all DVD formats and it will not burn CDs at all. This would interpret this as an indication that this problem is not related to a physical issue with the drive itself. Also, I have a second portable DVD burner and it works well with the laptop and desktops

I have tried various media brands and the result is the same, failure when using the drive with the laptop but success burning from my other two systems. The errors occur at various points in the burn process; the burn process will continue to a certain point and then freeze up forcing me to cancel the burn, close the burning program and power off the drive. When burning some DVD formats the drive works well. As I mentioned CDs always fail the burn process. The error occurs with every burn program I could throw at it including Nero 7 and CDBurnerXP.

I am at a loss given the other portable DVD drive works well with the laptop, the LG drive works well with the other systems, and some but not all DVD media work but not CDs. Does anyone have any idea about what might be going on and how to fix it?

Thanks in Advance

I agree this is a weird problem and I was probably too wordy in my initial post. Hopefully there is a Windows and/or DVD/CD burner guru who might hazard an opinion or possible solution to my problem. Here is an abbreviated version:

I installed the LG burner in an external case so I could move between three systems, (One is an HP laptop). The external case uses a USB 2.0 interface.

When plugged into my laptop USB port it will burn DVDs fine but fails every attempt to burn a CD. When plugged into my Vista and WinXP Pro towers it burns both CDs and DVDs fine.

I have tested the drive using different media including those recommended by LG. I have also tried various burning programs but no joy.

I have tried a different burner in the external case and it burns CDs when plugged into the laptop. I have never owned an LG drive before so I don't know if this is a peculiarity of the drive itself or a Windows problem. Since it burns when connected to my two towers I would assume that it is not a problem with the drive but is that true? If it is the drive I will need to RMA it but I don't want to do this unless I'm certain it is the hardware's fault. Any takers?

Obviously the external case is not suitable.
