对于可移动媒体驱动器和 CD-ROM 驱动器，仅当插入相应的媒体并准备接受访问时，<b>IsReady</b> 返回 <b>True</b>。
<p>以下代码举例说明如何使用 <b>IsReady</b> 属性：
<BLOCKQUOTE><pre><font face="宋体" SIZE=2>Sub ShowDriveInfo(drvpath)
Dim fs, d, s, t
Set fs = CreateObject("Scripting.FileSystemObject")
Set d = fs.GetDrive(drvpath)
Select Case d.DriveType
Case 0: t = "未知"
Case 1: t = "可移动"
Case 2: t = "固定"
Case 3: t = "网络"
Case 4: t = "CD-ROM"
Case 5: t = "RAM 磁盘"
End Select
s = "驱动器 " & d.DriveLetter & ": - " & t
If <font color="#FF0000">d.IsReady</font> Then
s = s & vbCrLf & "驱动器已就绪。"
Else
s = s & vbCrLf & "驱动器未就绪。"
End If
MsgBox s
End Sub</font></pre></BLOCKQUOTE>
