How to Detect Drive letter of a Flash drive from Batch Script

I saw a question on a popular forum asking How to detect drive letter of a flash drive  from cmd (Command prompt).

Detecting drive letter from command prompt is possible but a bit tricky, First we have to get into Diskpart then identify the disk type and obtaining the drive letter. Scripting this can be difficult. Instead going this route Why not try a easy VBScript ?

In this tutorial We will see a vb-script  which will detect the drive letter of a USB removable drive and output either on screen or on the cmd console.

‘ VBscript to detect the drive letter for a flash drive

Option Explicit
Dim objWMIService, objItem, colItems, strComputer
Dim strDriveType, strDiskSize
On Error Resume Next
strComputer = “.”

Set objWMIService = GetObject _
(“winmgmts:\\” & strComputer & “\root\cimv2″)
Set colItems = objWMIService.ExecQuery _
(“Select * from Win32_LogicalDisk”)

For Each objItem in colItems
Select Case objItem.DriveType
Case 1 strDriveType = “Drive could not be determined.”
Case 2 strDriveType = “Removable Drive”
Case 3 strDriveType = “Local hard disk.”
Case 4 strDriveType = “Network disk.”
Case 5 strDriveType = “Compact disk (CD)”
Case 6 strDriveType = “RAM disk.”
Case Else strDriveType = “Drive type Problem.”
End Select

If objItem.DriveType =2 Then
Wscript.Echo objItem.Name
Else

End If

Next

WSCript.Quit

As you can see, here we have 5 different type of drives which can be identified using this script. Those are

1.  Removable Drive
2. Local hard disk.
3. Network disk.
4. Compact disk (CD)
5. RAM disk.
