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

namespace Scsi.Multimedia
{
	[StructLayout(LayoutKind.Sequential, Pack = 1)]
	public class SetCDSpeedCommand : FixedLengthScsiCommand
	{
		[DebuggerBrowsable(DebuggerBrowsableState.Never)]
		private const byte ROTATION_CONTROL_MASK = 0x03;

		public SetCDSpeedCommand() : base(ScsiCommandCode.SetCDSpeed) { }

		public SetCDSpeedCommand(ushort readSpeed, ushort writeSpeed, RotationControl rotationControl)
			: this()
		{
			this.LogicalUnitReadSpeed = readSpeed;
			this.LogicalUnitWriteSpeed = writeSpeed;
			this.RotationControl = rotationControl;
		}

		[DebuggerBrowsable(DebuggerBrowsableState.Never)]
		private byte byte1;
		public RotationControl RotationControl
		{
			get { return (RotationControl)Bits.GetValueMask(this.byte1, 0, ROTATION_CONTROL_MASK); }
			set { this.byte1 = Bits.PutValueMask(this.byte1, (byte)value, 0, ROTATION_CONTROL_MASK); }
		}
		[DebuggerBrowsable(DebuggerBrowsableState.Never)]
