how to determine if machine has cdr ?

[mniccum]

I have many different models of CPQ/HP laptops of which some have burners and some don't. I have an unattended XP install that also installs all required apps. Roxio comes with the newer laptops that have a CDR/DVD. I was wondering if there was a way to determine if a machine had a CDR/DVD type device so I could determine if the machine needed Roxio. I would just install Roxio on all laptops but only the ones with CDR are licensed for it.

Maybe a VBS using WMI or some commandline exe....

Thanks,

I saw a post awhile back about determining Video card or some drivers or something. It might pertain to this, as XP will notice if it's a CDR/DVD drive (the different Icons) and it should save it somewhere. That would be my best guess.

I think GreenMachine posted a link to somewhere. I know a few others did too.

what about checking for a registry entry?

i would think it would add something 2 the registry...

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\CD Burning

That should tell you something. Alternativly, CDRECORD (perhaps called CDR Tools now?) can be used. It involves a reasonable knowledge of command scripting.

if you use WMI and enum all the CD drives, most burners have a CD-R/RW or something similar in the model string

basically look in device manager and open the dvd\CD-rom drives container. most burners will have some type of CDR text description.

or

look in HKLM\HARDWARE\DEVICEMAP\Scsi\Scsi Port 0\Scsi Bus 0\Target Id 0\Logical Unit Id 0

and look at the Identifier value

each of the 0's above will need to be changed to 1 alternately to walk the device connections

Now that you mention it, isn't there a command line interface to the Device Manager? DevCon, or something?

I wrote this script which works quite well to enumerate WMI class properties which when used with Win32_CDROMDrive I was able to determine if it was a burner.

strComputer = "."
strWMIClass = "Win32_CDROMDrive"

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from " & strWMIClass,,48)

For Each objInstance In colItems
   For Each objProperty In objInstance.Properties_
      If IsArray(objProperty) Then
         For iCount = 0 To UBound(objProperty)
            MsgBox objProperty.Name & vbTab & objProperty.Value(iCount)
         Next
      ElseIf IsNull(objProperty) Then
         MsgBox objProperty.Name
      Else
         MsgBox objProperty.Name & vbTab & objProperty.Value
      End If
   Next
Next
