Win32_DiskDrive Signature property

Question

Does anybody know what is the Signature property of the Win32_DiskDrive WMI class? Is it unique or users can change it like disk volume serial number?

Thanks.

Two comments that I think are very important for anyone following this path.

• It can be changed using the diskpart tool
• It is not reliable to access it via Signature - see Random value for disk Signature
