试下，如果返回为空，则表示失败。
在本机win8win8.1有效，不过好像在有些机器上没用。
可以查看附件，或则使用以下代码。应该注释的满全了。
随便建一个窗口工程，窗口代码帖入以下代码。

strResult += 磁盘类型: System.Convert.ToInt16(disk(DriveType).ToString())End IfMsgBox(strResult)NextEnd Sub总结：在VB.NET中，用API函数可以获取硬盘信息。原来熟悉API函数VB6程序员，可以对API函数声明进行适当的更改后，进行调用。利用FSO（文件系统对象）的Scrrun.DLL，也可以获得磁盘信息。在.net Framwork中，利用WMI可以获取更多的关于机器硬件的详细信息（参考System.Management命名空间）。
预先准备三个图标文件，用于树型控件中显示磁盘符号和文件夹的图像之用。
1、窗体上添加控件如下：
组合框控件 ComboBox1，树型控件 TreeView1，列表框控件 ListBox1，图像列表控件 ImageList1。
选中TreeView1，设置其ImageList属性为ImageList1。
2、设置属性
选中图像列表控件 ImageList1，在属性窗口里，选中属性Images，单击三个小点按钮，出现图像集合编辑器窗口，单击[添加按钮]，一一把准备好的图标文件进行添加，注意先后次序，如果不符合要求可以通过上下移动按钮重新改变次序。完成后单击[确定]。
运行图如下：
