Hi there,I am quite positive I am just overlooking something here but... well: a customer of mine will migrate from Vista to 7 in a few weeks. When I prepared his environment for that, I stumbled upon the the new GPO settings regarding Bitlocker. I was able to allow system drive encryption but I cannot find the right option to allow any other volume to be encrypted. Bitlocker, with the current configuration, will just state an error, that only the os volume may be protected with TPM. I would be very greatful for any advice on this. If I left any vital information out, let me know.With kind regardsChristoph SchmidtChristoph Schmidt || IT Consultant @ TOP TECHNOLOGIES CONSULTING || MCITP EA || My Blog || LinkedIn || XING

In Windows 7 any drive can be configured to use BitLocker but if you want to encrypt just a data partition and want it to be unlocked automatically you must also encrypt the operating system partition. You should also be able to encrypt other drives than the operating system partition by default. What is the exact error message and could you provide steps to what you did when you got the error message?

I use the following command, which worked well with Vista (as far asI remember): cmd /c manage-bde.exe -on D: -rp -rk z:\somepath\ -s -tp 12345678 The exact (german) error is: BitLocker-Laufwerkverschlsselung: Konfigurationstoolversion 6.1.7600 Copyright (C) Microsoft Corporation. Alle Rechte vorbehalten. Volume "D:" [WS-SOMEPC] [Datenvolume] FEHLER: Nur das Betriebssystemvolume darf mit dem TPM geschtzt werden. The last line translates like "ERROR: Only the operating system volume may be protected with TPM".Am I using the wrong approach here?Thanks for your help!

The -tp switch means "Adds a TPM And PIN protector for the OS volume." which is not applicable if you are encrypting a non-OS partition. So leave out "-tp 12345678" and off you go!
