Note: I know that there are ways for customers to get around the use of
the MAC Address of a network card for registering software. There may
be ways to get around the HD info as well.

Re: Re: programmaticall y obtain the hard disk's serial number from VBA?

Thanks. Unfortunately, the "GetVolumeSeria lNumber" function returns
the OS generated drive id, not the manufacturers's product serial
number that is stored on the drive's on-board ROM.

The OS drive ID WILL change if the user re-format's his HD. The Mfg
Drive serial number will not. What I need is VBA compatible code
that will make use of the Win32_PhysicalM edia.SerialNumb er funtion to
read and return the HARDWARE serial number of a selected drive.
Of course, the user COULD remove and replace any drive, but that
happens FAR less often than a re-format.

Re: programmaticall y obtain the hard disk's serial number from VBA?

Air Code: (be careful of news client created line breaks)

Code:

Function DiskZeroName() As String
Dim Buffer As String
Dim PathTxt As String
Dim FileNumber As Integer
On Error Resume Next
Kill "DiskZeroName*.*"
On Error GoTo 0
PathTxt = "DiskZeroName" & Format(Now(), "dddmmmddyyyyhhnnss\.\t\x\t")
Shell "RegEdit /E " & PathTxt & "
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\", vbHide
FileNumber = FreeFile
Open PathTxt For Binary As #FileNumber
Buffer = String(LOF(FileNumber), vbNullChar)
Get #FileNumber, , Buffer
Close #FileNumber
Buffer = StrConv(Buffer, vbFromUnicode)
DiskZeroName = Mid$(Buffer, InStr(Buffer, "Identifier") + 13)
DiskZeroName = Left$(DiskZeroName, InStr(DiskZeroName, Chr(34)) - 1)
End Function

On my laptop this returns
HITACHI_DK23FA-80.

I don't know if this is the number you want.
I don't know if it will work on other machines or other operating
systems.

Lauren,

Sorry I wasn't able to help. If you find a solution to this problem
please post it. I am also interested in other's comments about the
usage of this manufacturer HD ID as a "dongle."

Some of the earlier hacks no longer work and WMI is the way to use on current systems.

Easy in script if this is enabled and can be run in admin mode, for example create a file sn.vbs:
(Scott McNairy)

Code:

set svc = getobject ("winmgmts:root\cimv2")
set objEnum = svc.execQuery ("select * from win32_physicalMedia")
for each obj in objEnum
wscript.echo obj.GetObjectText_
next

and run this run in command mode (you can shell out to this) for example

cscript sn.vbs >result.txt

For VB code you will have to read the documentation yourself probably, or be more successful in
searching. WMI will work in VB but all the examples are in C++.

above script ref

and go up and down the tree.

Oh, I see that there are some WMI routines for disk info in Randy Birch's site VBnet (note this is
VB, not VB.net) but on cursory inspection these also seem to use scripting.

Re: Re: programmaticall y obtain the hard disk's serial number from VBA?

Thanks p. person. This is a cool way to retrieve what the OS THINKS
is the actual Mfg SN for drive 0. Since the value is retrieved from
the Registry, then, by definition, it can be wiped out by a
reformat/reinstall.

Please, someone correct me if I'm wrong: The "Win32_Physical Media"
class of the WMI library, actually reads and returns the drive
manufacturer's SN FROM the hardware ROM on a specified drive device.
This would be the serial number/identifier that was burned onto the
ROM when the drive was made. If so, THAT is what we need. Anything
less, is no better than what we have now -- and what we have now is
not adequate.

Can anyone point me in the right direction on this?

Thanks again for your help.

I would post the question in microsoft.publi c.win32.program mer.wmi

I would have expected that all WMI objects are actually precalculated, to read the actual number you
would need to be in a driver or with similar privileges. However by analogy with the MAC address, if
it has been spoofed there is an entry which can tell you this or reset it I forget which.

Re: programmaticall y obtain the hard disk's serial number from VBA?

In MSDOS it was easy to retrieve standard HD information,
but in Windows, hardware is virtualised, and you can't get
at it.

Windows does now provide a path to an interface for HD
serial numbers, but it is the SMART drive interface and
I don't know what you will get if SMART is turned off,
or if you have SCSI disks, or if you have Serial ATA disks,
etc.

I've never seen that work, but go ahead and try it:

Code:

'----------
Sub GetPhysicalSerial()

Dim obj As Object
Dim WMI As Object

Set WMI = GetObject("WinMgmts:")

For Each obj In WMI.InstancesOf("Win32_PhysicalMedia")
Debug.Print "SN: " & obj.SerialNumber
Next

End Sub

Re: Re: programmaticall y obtain the hard disk's serial number from VBA?

Hi David! Thanks for your response.

This works perfectly. However, it naturally returns SNs for ALL of
the HDs on my system. I need a way to return JUST the primary drive
SN (Drive 0). I tried inserting Debug.Print "SN: " & obj.name & ": "
& obj.SerialNumbe r, but the Name property returned only empty
strings.
Is there a way to limit the output to only the SN for Drive 0?

Thanks again.

Never mind. It appears that Drive 0 is always listed first.

Hi
I'm sure all the WMI methods will give the same result but in answer to your worry about whether the
result is really the serial number or whether it is just what the OS thinks it is .. see

Re: Re: programmaticall y obtain the hard disk's serial number from VBA?

Thanks a lot PP! The last article was VERY helpful.

We have now tested my WMI code on several Windows PCs, all XP or 2000
machines. In every case, the drive ID's returned exactly matched the
drive serial number originally provided by the drive mfg! I don't
know if this will work on EVERY PC. So far, it looks good.

The bottom line for ALL of this is that there is a growing need to
identify a particular PC with absolute certainty. This approach may
not be the final method, but it seems to move in that direction.

It doesn't identify my PC :~) I get a blank for the serial

Interesting. Mind saying what is your OS, and primary HD brand name?
