Hard drive serial (manufacturer) number

Skud · 17-05-2007 2:00pm #1

Just wondering if it is possible to retrieve hard drive manufacturer serial number... I used this example here:

http://www.codeproject.com/csharp/hard_disk_serialno.asp

where it accesses the wmi. Problem is, it doesn't work all the time. I've noticed if a computer is running .net framework 2.0 (i used 1.1) then it doesn't work. I don't have the ability to test it on 3.0

the problem is when trying to access the SerialNumber variable in the Win32_PhysicalMedia API.

 // get the hardware serial no.
    if (wmi_HD["SerialNumber"] == null)
     hd.SerialNo = "None";
    else
     hd.SerialNo = wmi_HD["SerialNumber"].ToString();
    
    ++i;

Can anybody point me in the right direction? It just displays None, when I try run it on .net 2.0

you could try this VBScript here, see what results you get.

[PHP] strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
Set colSettings = objWMIService.ExecQuery _
("Select * from Win32_PhysicalMedia")
For Each objPhysicalMedia in colSettings
Wscript.Echo "Serial Number: " & _
objPhysicalMedia.SerialNumber
Next[/PHP]

might be your operating system doesn't support it? i know highly unlikely..but just incase.
could be just doesn't have one!

that didn't work. I have an idea what might be going wrong with it though... Comes with a default hard drive password. Maybe that's why windows wasn't picking it up, being built with that.

BTW for future information, Windows Genuine Advantage records the serial of the hard drive. If that doesn't, then it's not recognised in windows
