Question

Is there an easy way to detect if a disc is inserted in the DVD drive? I don’t care what kind of disc (CD, DVD or Blu-Ray)?

Answer 1

Use WMI to detect if disk in CD/DVD drive:

foreach (var drive in DriveInfo.GetDrives()
                               .Where(d => d.DriveType == DriveType.CDRom))  
MessageBox.Show(drive.Name + " " + drive.IsReady.ToString()); 

from here.

DriveType Enumeration can help you what kind of disc:

• CDRom : The drive is an optical disc device, such as a CD or DVD-ROM.
• Fixed : The drive is a fixed disk.
• Network : The drive is a network drive.
• NoRootDirectory The drive does not have a root directory.
• Ram : The drive is a RAM disk.
• Removable : The drive is a removable storage device, such as a floppy disk drive or a USB flash drive.
• Unknown : The type of drive is unknown.

for kind of CD/DVD/Blue-Ray see IMAPI_MEDIA_PHYSICAL_TYPE enumeration:

• UNKNOWN
• CDROM
• CDR
• CDRW
• DVDROM
• DVDRAM
• DVDPLUSR
• DVDPLUSRW
• DVDPLUSR_DUALLAYER
• DVDDASHR
• DVDDASHRW
• DVDDASHR_DUALLAYER
• DISK
• DVDPLUSRW_DUALLAYER
• HDDVDROM
• HDDVDR
• HDDVDRAM
• BDROM
• BDR
• BDRE
• MAX

your code may be like this:

public bool IsDiscAvailable(int driveNumber)
{
    MsftDiscMaster2Class discMaster = new MsftDiscMaster2Class();
    string id = discMaster[driveNumber];

    MsftDiscRecorder2Class recorder = new MsftDiscRecorder2Class();
    recorder.InitializeDiscRecorder(id);

    MsftDiscFormat2DataClass dataWriter = new MsftDiscFormat2DataClass();
    if (dataWriter.IsRecorderSupported(recorder))
    {
        dataWriter.Recorder = recorder;
    }
    else
    {
        Console.WriteLine("Recorder not supported");
        return false;
    }
    if (dataWriter.IsCurrentMediaSupported(recorder))
    {
        var media = dataWriter.CurrentPhysicalMediaType;
        if (media == IMAPI_MEDIA_PHYSICAL_TYPE.IMAPI_MEDIA_TYPE_UNKNOWN)
        {
            Console.WriteLine("Unknown media or no disc");
        }
        else
        {
            Console.WriteLine("Found disc type {0}", media);
            return true;
        }
    }
    else
    {
        Console.WriteLine("Disc absent or invalid.");
    }
    return false;
}

from here.
