Windows 10: auto bitlocker unlock feature disabled for fixed and removable data drives associated with...

Hi I am trying to install windows 10 to my computer. currently using windows 11.But bitlocker has been acting for all my drives.I tried in many ways to disbable bitlocker protection, but not working.Last time I used " manage -bde- status " and final result came "Bitlocker drive encryption can not be turned off on the operating system drive until the auto unlock feature has been disabled for the fixed data drives and removable data drives associated with this computer"How to solve this?

:)

 

Fixed Drive Detected as Removable in Bitlocker

My system has 2 data drives in addition to the boot drive which is SSD. While windows detects both drives as fixed drives Bitlocker reports one of the drives as removable and so I cannot set it to auto-unlock. Any suggestions on how to change this behavior
and make Bitlocker report correctly?

 

Bitlocker not auto unlocking

So, we have many systems about 15 of them in which we have a removable device USB that is encrypted by Bitlocker. We have set the system up so that the drive auto unlocks. However, if the OS is rebooted the drive will not auto unlock. I have even tried running the power shell script Enable-BitLockerAutoUnlock -MountPoint "c:" I get no error messages and according to the output I get it seems to have unlocked it, but it has not, it is still locked. So, I must manually right click the drive--unlock--put the password in and then it unlocks. But when the OS reboots it will lock again. Also, I can see that the drive I am trying to auto unlock has the status of drive is auto unlocked is set to true when I run a BitLocker status.

What we are trying to do is when the OS does reboot the drive autounlocks without us having too manually do so. We have an application that writes data to this USB drive, but when it is locked the application cannot access the drive so it cannot save the data to it. Running this command after manage-bde -autounlock -enable H: before I run the other gives me the error message that the volume is locked. Running Win 10 22H2



This data on the USB device is connected to the same system or the host. Another words the USB is connected to the USB port on the computer in which it was originally encrypted and is now connected, and the data being transferred goes from computer to USB, it does not travel anywhere outside of the USB. So, this data would be considered at rest, and it my understanding that a device encrypted by BitLocker that is already unlocked, will not lock unless when some variable changes, such as taking this USB drive out of this machine and connecting it to another machine, but this is not the case. So, if this is true then what would cause BitLocker to lock the drive just by rebooting Windows, and then the auto unlock feature to not work? I am guessing if I knew that I could fix the auto unlock feature.

 

Enable Bitlocker auto-unlock without system drive encryption

1. turn off bitlocker on the drive you want to auto-unlock
   
2. mount this drive as a removable drive
   i.e plug it into a usb attached drive unit such as StarTech or many others
   
3. boot the system and bitlock the drive and turn on auto-unlock
   
4. shutdown the system
   
5. mount the drive as a permanent drive
   
6. reboot the system and the drive will auto-unlock because windows now thinks
   that it is a removable drive
   

Works For Me with no problems
