that is not the physical serial number, but the logical volume serial. Totally different. Besides, the volume serial can be changed with software, it should not be considered neither unique not secured to use in protection / licence mechanisms

have a look at this dll (free), it has all you need's%20DLL.html

You could also do it yourself using WMI, but why the trouble if this dll works well ? I'll test it myself when I have time

that source code looks good also, if you don't need or don't want to use WMI (can be slow)

there is even a WMI example below in the same page
What you are mentioning is correct.
My suggested code is only for the logical volume serial...

But here's another one for physical harddisk serial number...

IDE harddisk serial number
