I don't have another drive
Also I am using windows 7.
Can you tell me command in cmd to disable autounlock option for bitlocker? May be that would help as all this started when I checked the automatically unlock on this computer option

Option Two in the tutorial below can help show you how to turn off BitLocker Auto-unlock using the command prompt. Hopefully it'll allow to work like it did before afterwards.

Accessing locked external HDD

Brink,
Option 2 to Unlock a Data or Removable Drive in a Command Prompt was very useful for a locked USB drive. However, was not successful for accessing external backup HDD. Tried cmd prompt options for password and drive recovery key, but to no avail.

Was given the following error in the cmd window after typing in: manage-bde -unlock G: -password
Bitlocker Drive Encryption: Configuration Tool version 6.1.7601 Copyright <C> Microsoft Corporation. All rights reserved.

ERROR: An error occurred <code 0x8004100e>:
Invalid namespace

Any ideas? Not receiving the prompt to enter the drive password....

Also tried the cmd prompt and string for the recovery key and to no avail. Received the same error after typing in: manage-bde -unlock G: -rp (then recovery key string)

Any ideas, solutions would be greatly appreciated.
Many thanks.

Hello jbw, and welcome to Seven Forums.

See if this below may help with the MBAM error 0x8004100e.

You might see if running a sfc /scannow command to see what it finds, and the command above again after SFC repairs any files if needed may allow it to work afterwards.

Bitlocker issue

Hi Team,

I have a problem... I have 3 hdds in my pc of which one is locked through bitlocker. This is not the main hdd where os is loaded. So I accidentally formated my main hdd without creating any recovery keys. Would I be able to use the locked hdd.

Hello Edwardeniz, and welcome to Seven Forums.

You will need at least the BitLocker password or recovery key to be able to unlock the data drive.

If you have the password (if used), then you should be able to use any option in this tutorial to unlock it with.

Hello There,
I tried to unlock my external HD via Command prompt and via Bitlocker UI but both methods failed to unlock my drive.
The Encryption key that i have is the same and it does matches the recovery key Identification but every time i type it via UI it says that it is incorrect and via command prompt it says the password failed to unlock drive G.
Please refer to the attached screen shots and suggest what should i do with it.

Thanks in Advance.
AH Khan

Hello AH Khan, and welcome to Seven Forums.

Did you try unlocking the drive using the password instead of the recovery key?

If so, you could also try the method in the tutorial below to recover the drive, but it requires another drive that's at least the same size.
