Obtener datos como la etiqueta y el sistema de archivos de una partición:

Option Explicit
Private 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
Private Sub Command1_Click()
Dim lVSN As Long, n As Long, s1 As String, s2 As String
Dim unidad As String
Dim sTmp As String
On Local Error Resume Next
unidad = Trim$(Text1)
s1 = String$(255, Chr$(0))
s2 = String$(255, Chr$(0))
n = GetVolumeInformation(unidad, s1, Len(s1), lVSN, 0, 0, s2, Len(s2))
sTmp = Hex$(lVSN)
Label1(0) = s1
Label1(1) = Left$(sTmp, 4) & "-" & Right$(sTmp, 4)
Label1(2) = s2
End Sub
Private Sub Form_Unload(Cancel As Integer)
Set Form1 = Nothing
End Sub

Se necesitará de Text1 para ingresar la letra de la partición. Por ejemplo: "C:\", Command1 para obtener la información y Label1 indexado para mostrar la información, espero les sirva
