Temp2 = String$(255, Chr$(0))

Res = GetVolumeInformation(strDrive, Temp1, _

GetSerialNumber = SerialNum

End Function

Private Sub cmdSerial_Click()
Call MsgBox(GetSerialNumber("C:\"))
End Sub
Tried Ruchi's answer because I was curious too and works well. Only comment I have is that if you want to compare it to what you get at the command prompt by typing "dir", use the hex function:

Call MsgBox(Hex(GetSerialNumber("C:\")))

Sorry for the delay..

I worked out your answer, but it only gives the volume serial number.  But I want to find the physical id of the hard disk which was created by the manufacturer of the disk.
