Since nobody has come up with positive answers to your questions, here is what you probably did not want to hear. Three times over: three negative answers for the price of one.

You can't do any of these things in DOS.If you're interested in a Windows Scripting Host solution, then that might be possible. The trouble with WSH is that every user has a different version, which means that things that work perfectly on your machine may give a runtime error on your user's machine; and Vista is another story entirely.

I'm guessing here, but I suspect that you want this for an install, because otherwise you would not be wanting to enumerate the host machine's drives. You simply can't write a proper install in Windows batch. It's nowhere near powerful enough. For a free and quite capable (if somewhat under-documented and exceedingly hard-to-learn) install system try Nullsoft Install at http://nsis.sf.net.

Here it is
strComputer = "."
Set objWMIService = GetObject("winmgmts:"  & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colDisks = objWMIService.ExecQuery ("SELECT * FROM Win32_LogicalDisk")
For Each objDisk in colDisks
 if objDisk.DriveType = 5 Then
 Wscript.Echo "DeviceID "& objDisk.DeviceID & " is a CD." 
 End if
Next

I thought you would be able to manage that on your own.
strComputer = "."
Set objWMIService = GetObject("winmgmts:"  & "{impersonationLevel=impersonate}!\\" & 
 
strComputer & "\root\cimv2")
Set colDisks = objWMIService.ExecQuery ("SELECT * FROM Win32_LogicalDisk")
For Each objDisk in colDisks
 if objDisk.DriveType = 5 Then
 Wscript.Echo "There is a CD." 
 Exit for
 End if
Next

It i's giving a syntax error because 2 linebreaks got introduced while cutting and pasting. Replace lines 2-4 with the original line 2 and it works.

strComputer = "."
Set objWMIService = GetObject("winmgmts:"  & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colDisks = objWMIService.ExecQuery ("SELECT * FROM Win32_LogicalDisk")
For Each objDisk in colDisks
 if objDisk.DriveType = 5 Then
 Wscript.Echo "There is a CD." 
 Exit for
 End if
Next

Sorry, misunderstood the question. That code is checking for the kind of drive (CD, floppy, network, etc). Not for what is in it.

Try this one. It reports on the volume name of the CD. If there is no CD in the drive then the volume name will be empty.

If you don't like the message then substitute

Wscript.Echo "There is a CD." in line 6.

strComputer = "."
Set objWMIService = GetObject("winmgmts:"  & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colDisks = objWMIService.ExecQuery ("SELECT * FROM Win32_LogicalDisk")
For Each objDisk in colDisks
 if objDisk.DriveType = 5 and objDisk.VolumeName <> "" Then
 Wscript.Echo "DeviceID "& objDisk.DeviceID & " is a CD: " & objDisk.VolumeName
 Exit For
 End if
Next
