Ever wonder how programs like Nero work? They make their own SCSI libraries... like this!
using System;
using System.ComponentModel;
using System.Diagnostics;
using System.Runtime.InteropServices;
using Helper;

namespace Scsi.Multimedia
{
	/// <summary>This feature indicates that the drive is capable of reading a disc with the MRW format.</summary>
	[Description("This feature indicates that the drive is capable of reading a disc with the MRW format.")]
	[StructLayout(LayoutKind.Sequential, Pack = 1)]
	public class MountRainierRewritableFeature : MultimediaFeature
	{

		private static readonly ScsiCommandCode[] __SupportedOperations = new ScsiCommandCode[] { ScsiCommandCode.GetEventStatusNotification, ScsiCommandCode.Read10, ScsiCommandCode.Read12, ScsiCommandCode.ReadCapacity, ScsiCommandCode.ReadDiscInformation,

		public override FeatureSupportKind GetSupport(ScsiCommand command)
		{
