I am trying to get the HARDWARE Serial Numbers of hard-disk drives (which includes SSDs) with WMI (Windows Management Instrumentation):

Class: Win32_DiskDrive
Namespace: root\CIMV2

Now, a customer's computer contains 4 Western Digital hard-disk drives:

WDC WD2002FYPS-02W3B0 ATA Device
WDC WD2003FYYS-02W0B0 ATA Device
WDC WD3000GLFS-01F8U0 ATA Device

And these are the serial numbers of these 4 hard-disk drives I got with the above WMI query:


Please note that these serial-numbers are very similar, so I cannot believe these are the real serial-numbers of these hard-disk drives.
So I used a professional hardware information program (HWiNFO) to compare these serial-numbers with those detected from HWiNFO, and they were totally different.

So I wonder whether it is possible to query the REAL hardware serial-numbers of hard-disk drives by using WMI?
