获取硬盘序列号报错: IDE identify command not supported。

Question

获取硬盘序列号报错，以下为方法，什么情况下会报 IDE identify command not supported。

          #region GetHddInfoNT

        private static HardDiskInfo GetHddInfoNT(byte driveIndex)

您好，看了一下你的代码大体上是使用DeviceIoControl来获取硬盘序列号的，这是一种很常见的读取方式，一般情况下当硬盘类型不支持，驱动程序问题，或者是系统环境限制等，都可能会出现此类错误。
