How can I obtain the serial number of a drive that a spreadsheet is
installed on from within the same EXCEL spreadsheet?

Try:

Sub DriveSerial()

Dim fs As Object
Dim d As Object

Set fs = CreateObject("Scripting.FileSystemObject")
Set d = fs.GetDrive(fs.GetDriveName _
(fs.GetAbsolutePathName(ThisWorkbook.Path)))
MsgBox d.SerialNumber

End Sub

Hope this helps

A couple of ways (to get different answers :-))


'Using FSO

Function DiskVolumeId(Drive As String) As String
Dim FSO As Object
Set FSO = CreateObject("Scripting.FileSystemObject")
DiskVolumeId = Format(CDbl(FSO.Drives(Drive).SerialNumber))
End Function


'Using API

Declare Function GetVolumeInformation Lib "kernel32" _
Alias "GetVolumeInformationA" _
(ByVal lpRootPathName As String, _
ByVal lpVolumeNameBuffer As String, _
ByVal nVolumeNameSize As Long, _
lpVolumeSerialNumber As Long, _
lpMaximumComponentLength As Long, _
lpFileSystemFlags As Long, _
ByVal lpFileSystemNameBuffer As String, _
ByVal nFileSystemNameSize As Long) As Long



Function DriveiD(Drive As String)
Const cMaxPath As Long = 256
Dim nTemp
Dim sTemp As String
Dim nRet As Long
Dim nVolSerial As Long
Dim sVolName As String * cMaxPath
Dim nMaxCompLen As Long
Dim nFileSysFlags As Long
Dim sFileSysName As String * cMaxPath

If Right(Drive, 1) < "\" Then Drive = Drive & "\"
nRet = GetVolumeInformation(Drive, sVolName, cMaxPath, _
nTemp, nMaxCompLen, nFileSysFlags, _
sFileSysName, cMaxPath)
sTemp = Format(Hex(nTemp), "00000000")
sTemp = Left(sTemp, 4) & "-" & Right(sTemp, 4)


DriveiD = sTemp
End Function

Hi Bob,
If you agree, I prefer:

Function DiskVolumeId(Drive As String) As String
DiskVolumeId = Hex(CreateObject("Scripting.FileSystemObject") _
..Drives.Item(CStr(Drive)).SerialNumber)
End Function

Hi Michel,

It certainly looks good to me. Maybe, just to allow for any type of input
(C, C:, C:\, C:\myDir, etc.)

Function DiskVolumeId(Drive As String) As String
Dim sTemp As String
Dim iPos As Long
iPos = InStr(1, Drive, ":")
Drive = IIf(iPos 0, Left(Drive, iPos), Drive & ":")
sTemp = Hex(CreateObject("Scripting.FileSystemObject") _
.Drives.Item(CStr(Drive)).SerialNumber)
DiskVolumeId = Left(sTemp, 4) & "-" & Right(sTemp, 4)
End Function

Regards

Bob
