推荐答案

签名"属性是在 Windows XP 中引入的，用于用作共享群集磁盘的磁盘.据我了解，它是在磁盘第一次连接到 Windows 系统时创建的，即使磁盘通过另一个控制器连接(或在集群场景中甚至通过另一台计算机连接)也不会更改.

The "Signature" property was introduced with Windows XP and is used for disks that are used as shared cluster disks. In my understanding it is created the first time the disk is connected to a windows system and will not be changed even if the disk is connected via another controller (or in a cluster scenario even via another computer).
