Hi
The WMI class Win32_DiskDrive has a property Signature and it correctly
shows
disk signature for MBR disks.
However for GPT disks this filed is null. (Since GPT signature is GUID and
Signature property is of type INT32 it is not possible to show it here
anyway).

Is there any other new WMI class to represent GPT disks?
Is it possible to get GPT disk signature from WMI?

BTW, I am using Windows 2008 RC1.

Thanks and Regards
