Answer 1

you can try this vbscript

Const CDROM = 4
Set objFS=CreateObject("Scripting.FileSystemObject")
Set shell = CreateObject("Shell.Application")
For Each drives in objFS.Drives
  If drives.DriveType = CDROM Then
    cd=drives.DriveLetter & ":\"    
    'Eject           
  End If
Next
Do
 shell.Namespace(17).ParseName(cd).InvokeVerb("E&ject") 
 WScript.Sleep 1000 'in ms
Loop While 1=1

save as eject.vbs run it as

c:\test> cscript //nologo eject.vbs
