cdb + jump drives

Recommended Posts

Something seems to go wrong with CDB (both the alpha and stable versions) if I have a USB jump drive attached: if I decide to make a data cd/dvd the program immediately reports:

Object reference not set to an instance of an object.

at DVDPROX2Lib.IDVDWriterPro2.InitDrives(Boolean bUseNTASPI)

at AxDVDPROX2Lib.AxDVDWriterPro2.InitDrives(Boolean bUseNTASPI)

at v.i()

at v.bi(Object A_0, EventArgs A_1)

at System.Windows.Forms.Form.OnLoad(EventArgs e)

at System.Windows.Forms.Form.OnCreateControl()

at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)

at System.Windows.Forms.Control.CreateControl()

at System.Windows.Forms.Control.WmShowWindow(Message& m)

at System.Windows.Forms.Control.WndProc(Message& m)

at System.Windows.Forms.ScrollableControl.WndProc(Message& m)

at System.Windows.Forms.ContainerControl.WndProc(Message& m)

at System.Windows.Forms.Form.WmShowWindow(Message& m)

at System.Windows.Forms.Form.WndProc(Message& m)

at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m)

at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m)

at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

(This is for the alpha; similar but not identical message for the stable version).

This has happened to me on two separate computers ( Dell Dimension 8300, Presario 1750NX) both running XP, sp2 and the latest updates. At a guess, CDB sees the jump drive, thinks it may be a CD player/burner and tries to get its capabilities; and of course fails. If I unplug the drive and restart CDB, then the program works as it should.

Is this a known issue, and is there a work-around (apart from unplugging the drive)? Perhaps the easiest solution would be for CDB to allow the user to tell the program that drive x isn't to be scanned for capabilities (if that's what's going on).

(This has also been reported via CDB's built-in error-reporting system).
