Question

We have created two partitions in removable drive(USB). One of the partition is active and the other is hidden. We are trying to access the hidden partition in Win PE 3.0 environment using WMI. VBScript code snippet used to detect the partitions is given
below:- 
SetobjWMIService = GetObject("winmgmts:"_&
"{impersonationLevel=impersonate}!\\"&
strComputer & "\root\cimv2")
SetcolDisks = objWMIService.ExecQuery
Select * from Win32_LogicalDisk")
It will return the partition which is active but fails to list the partition which is hidden. The same piece of code was supported on WinPE 2.0

Answer 1

I am giving the complete code, may be you are able to understand better. We are using Win32_LogicalDisk to retrieves the complete information of all the drives (like C:, D:) including removable drives. 
Function
LocalDriveFound()
    strComputer =
SetobjWMIService = GetObject("winmgmts:"_
"{impersonationLevel=impersonate}!\\"&
strComputer & "\root\cimv2")
SetcolDisks = objWMIService.ExecQuery
"Select * from Win32_LogicalDisk")
ForEachDiskDrive
IncolDisks
        DriveLetter = Left(DiskDrive.Name,1)
        DriveType = DiskDrive.DriveType
        VolumeName = DiskDrive.VolumeName
        WScript.echo Driveletter &
"|"& Drivetype &
"|"&VolumeName
SelectCaseDriveType
Case2 ,3  
'Fixed or removable
If(VolumeName=USBVolumeName)
Then
If(DriveLetter<>
"Z")
Then
                    ChangeDriveLetterWithMountvol DriveLetter,
"Z"
EndIf
                bIsLocal=
True
EndIf 
If(VolumeName=USBRootName)
Then
If(DriveLetter<>
"Y")
Then
                    ChangeDriveLetterWithMountvol DriveLetter,
"Y"
EndIf
                bIsLocal=
True
EndIf 
CaseElse
EndSelect
Next
SetDrives =
Nothing
SetFileSystemObject =
Nothing
End
Function
