A Simple BitLocker Utility

[hunterman223]

Hi, I have found out that it is not possible to re-lock a BitLocker encrypted data drive without either rebooting or via a command in command prompt. My solution (of course) was to create a simple batch program that allows you to either lock or unlock a drive. I have made comments in the file itself to aid in changing parameters, switches, etc. I have only tested it out in Windows 7, but if Vista uses manage-bde it should work. The program requires administrative privileges, so it is best to create a shortcut and change the properties of it. Then you can add your own fancy icon.

Hopefully someone may find this remotely helpful. For safety's sake I will post the contents of the batch file here. To make it into a real file, you paste the contents into notepad, save as, all file types, and add .bat to the end of the name. Let me know if you have questions.

Code: Select all

:: Simple batch program to change the locked state of BitLocker encrypted drives.
:: This program can be redistributed or edited as you wish.
:: See "manage-bde -help" for help with switches and parameters.

@echo off

manage-bde -lock E: -fd

cls
echo The Drive has Been Successfully Locked.
echo.
pause
exit

:unlock
cls
echo Unlocking Drive...
echo.
manage-bde -unlock E: -pw
:: Edit E: to reflect your BitLocker encrypted drive.
:: Edit -pw to reflect the way you unlock your drive. (e.g. -pw for password)
cls
echo The Drive has Been Successfully Unlocked.
echo.
pause

Edit: Corrected minor error in code.
