新买来的硬盘是未初始化的，以我的理解就是没有引导扇区的，通常是没有MBR，如下图磁盘1，右边有大小，但显示“未分配”，

左边显示“没有初始化”， 点鼠标右键就可以【初始化磁盘】。

![Center][]

初始化时可以选择MBR和GPT， MBR方式顶多支持2T硬盘的。

![Center 1][]

初始化后

![Center 2][]

初始化后可以新建简单卷了，之前是不行的：

![Center 3][]

CreateDisk(1, 3) 就是把磁盘1分为3个分区

![Center 4][]

奇怪，如果只分1个区，就是自动以NTFS格式化掉， 而分3个区，还会提示是否格式化。

如果想回到刚买回来的空白状态怎么办呢？ 用DestroyDisk()就可以了
