That was my guess. That's probably the most common problem, and one that I had to solve once. Long ago, I found code on the .NET that showed how to do this with the specified CDROM Drive. I'm afraid I can't find it now. It can be done with MCI, however. I've done it. Keep searching, I guess! Sorry I can't be more help.

I have done what you are saying with [DllImport] attribute, and I have successfully used SendMciString command but I cannot control which of my ejectable drives to eject. I have a cdrom and a cd writer, with SendMciString i ejected the first one. I'm intrested to choose what drive to eject.

I have always done this in native code using the functions in mmsystem.h (e.g. SendMCIString() and SendMCICommand() ). I think I can do this in .NET with Delphi, but C# needs to use PInvoke. Is this what you're saying you've tried? What do you need to do that it doesn't do?
