Question

I have this code:

DriveInfo dr = new DriveInfo(@"E:\");

if (dr.IsReady == false)
{
  MessageBox.Show("Drive E: is not ready. Please insert a blank DVD medium.");
}

So, I insert a blank DVD in the drive and run the code. What am I missing?

Thanks a lot

Answer 1

DriveInfo.IsReady on the blank DVD will return false.

If you need to distinguish if a blank disc is there, you’ll need to use a different library. Here is a program that includes a interop wrapper around IMAPI2 (Window’s Image Mastering API): http://www.codeproject.com/KB/miscctrl/imapi2.aspx

Use the interop wrapper and call

IDiscFormat2Data discFormatData = new MsftDiscFormat2Data();
if (discFormatData.CurrentMediaStatus == IMAPI_FORMAT2_DATA_MEDIA_STATE.IMAPI_FORMAT2_DATA_MEDIA_STATE_BLANK)
{
    ...
}
