[SOLVED] Bitlocker encrypted Drives. Procedure before BIOS Update 2703

Level 8


I'm preparing to update my Z690-I to Version 2703.  I have 2 drives. 

So I've suspended  Bitlocker on Drive C:. 

But what about Drive D ? Here I can only decrypt the whole drive. This takes a long time. Maybe there is a  more convenient solution.

Does anyone know how to manage this?


This is quite complicated. I've set a preboot pin. What will happen after the Update? Will this TPM Pin be lost? 

I've decrypted drive D already. Drive C: is bitlocker suspended.  


Decrypted all drives. Checked with:  manage-bde -status

Preboot pin was deleted after decryption. 

BIOS Update went smooth. 

Bitlocker re-enabled. Set Pin and Encrypting process running.


BESIDES: Why do I have to reCAPTCHA every minute?

I don't encrypt my OS drive - that's just for the OS and installed programs. However, I do Bitlocker encrypt my data (and several backup drives) and for those I use a Bitlocker password. I don't rely on TPM keys. That's makes it super easy and there is never any risk of losing or forgetting passwords as those are stored in a password database (also encrypted) with a master password and stored in multiple locations.

Just the way I do it, but it works well and I don't need to be concerned about complications if a drive fails, gets corrupted or I lose the TPM keys. Good idea to store your Bitlocker recovery key(s) in a separate password database as well.  

I also choose not to use OS RAID, I'd be too concerned about restoring data if a drive failed. I do have RAID enabled on my NAS backup, but that's easy just to plug in another drive if one fails.
