functions FolderExists() and FileExists() causes an error "Insert disk in drive X:", when check an empty dvdrom. I don't know, is this a bug, but it causes problems
I've tried to use DiskIsReady("") function, but I didn't understand, how to use it.

This isn't a bug. That's standard windows practice. If some drive is not ready, no API operation is allowed on it.

Code:
if(DiskReady("DRIVE:"))
{
//some  stuff
}
else {
//disk not ready
}


For more control, you can use file system object. See MSDN for more details

Hi, you can uses the DiskCore, and set disk name with
Code:
diskcore1.cmd(null, "diskname=c");


Code:
  if(diskcore1.IsBlank)
  {
      //the disk is blank or not exists
  }
  else
  {
  }





Code:
if(diskcore1.DiskType<2)
{
  alert("disk not exit");
}




Or, you can use ActiveX object "FSO" function "DriverExists" and get the disk type

Code:
var fso = new ActiveXObject("Scripting.FileSystemObject");
if( ! fso.DriveExists("d") )
  alert("Dirver D is not Exists");

Ok... As I expected..
then this is what you need
http://msdn.microsoft.com/en-us/library/x681abd9(v=vs.84).aspx

Code:
var fso = new ActiveXObject("Scripting.FileSystemObject");
var disk = fso.GetDrive("J:"); //change with your drive

if(disk.IsReady)
{
//disk is ready and contains media
}
else {
//disk not ready...
}


I don't know why but I too faced problems with XWidget built-in DiskIsReady(). This is a bug... needs to be fixed. Meanwhile ActiveX is the only workaround.
