Question

Im writing a batch script to run on a flash drive. I need to validate the volume serial number of flash drive inside the code, therefore nobody should be able to run it from a different location.

Does anyone know how to validate serial number inside a batch file?

Example:

IF %VOL%==ABCD GOTO A ELSE EXIT

Answer 1

Although there are several different ways to achieve the same thing, the original DOS/Windows command intended to manage volumes and serial numbers is VOL:

@echo off
for /F "skip=1 tokens=5" %%a in ('vol %~D0') do set Serial=%%a
if %Serial% equ ABCD-EF01 do (
    echo Valid serial number!
)
