  Jonny,
  sorry for the long post that follows. If you need to address issues about burning CD's and DVD's, you may find some interesting information here, where it's mentioned the ICDBurn interface. Quite interesting.

  If you "only" want to detect the actual capabilities of your drives, and what you get via DriveType (DriveInfo.DriveType), you will have to use the DeviceIoControl API that will get you all the information you want, and maybe some more. As usual,you won't get away with a single call. You need to set up some structures, enums, and all also CreateFile and CloseHandle. What follows is a crude example (it looks huge only because there are all the enum's) that you will have to adapt to your needs.

  public class DriveInfoEx {

  const int IOCTL_STORAGE_GET_MEDIA_TYPES_EX = (0x0000002d << 16) | (0x0301 << 2);

  const uint AccessReadWrite = 0xc0000000;

  const uint ShareReadWrite = 3;

  const uint OpenExisting = 3;

  [DllImport ("kernel32.dll")]

  private static extern bool DeviceIoControl (IntPtr hDevice, uint dwIoControlCode, IntPtr lpInBuffer, int nInBufferSize, ref GET_MEDIA_TYPES lpOutBuffer, int nOutBufferSize, ref UInt32 lpBytesReturned, IntPtr lpOverlapped);

  [DllImport ("kernel32.dll")]

  private static extern IntPtr CloseHandle (IntPtr hObject);

  [DllImport ("kernel32.dll")]

  As I don't have a DVD-RW on hand at the moment, I don't know if it will work for you, but it should be a starting point. My DVD/CD is correctly reported as a DVD Drive (through the DeviceType), but it insists it only supports CD-ROM and Removable Device (the latter as Read/Write). Also, it doesn't seem to work with floppy drive.

  PS: I wan't to create an application that display the model name of an cdrom or cd-rw or,,,
  
  

• MSGTSC_Test

  I dont think you can really display the model name as such in C# as this would require you to go low level.

  you could again maybe use Win32 API calls, check msdn for this. Best way would probably to get devices from device manager, if there is a way to access it via API

  
  
  

• CityOfOrlando

  in .NET 2.0 you can use the System.IO namespace.

  In this, you can use the DriveInfo class and you can then go through the collection of drives returned and get its information you require.

   

  Example:

   

  System.IO.DriveInfo[] theDrives = System.IO.DriveInfo.GetDrives(); foreach (DriveInfo currentDrive in theDrives) {    MessageBox.Show("DriveName: " + currentDrive.Name + Environment.NewLine + "Drive Type: " + currentDrive.DriveType.ToString() + Environment.NewLine + "Drive Format: " + currentDrive.DriveFormat); }

  ok.it works.....but what is the result For example the device name........(I talk about the last result, the first is not working: error: "The device is not ready")
