Unable to unlock USB drives encrypted/locked with Bitlocker To Go

Hey All,

Recently my company provided me with a Windows 10 SOE image as part of a UAT. The image includes Symantec Endpoint Encryption which utilizes Bitlocker for encryption.

I went through all of the motions with the C:\ drive to be encrypted and even printed the recovery key. Well, at some point I plugged in a few My Passport USB drives and they became locked by Bitlocker To Go. Everytime I try to unlock or click on these drives it asks for the 48-bit key which I don't have because I never was prompted to encrypt/lock these drives.









IT says that there are no keys stored on the servers for these USB drives and suggested that this would be a "local" encryption. However, they also stated that they wouldn't be encrypted unless I was prompted about it. So, there's this mystery about how these USB drives came to be locked.


I've been doing some research and the closest I've come is getting some output about the protectors:
Code:

I've tried to copy the .bek file to another non-encrypted/locked USB but get:

Code:

I've tried all of the passwords (even blank) I have in an attempt to unlock the drive:

Code:

When I search my laptop by either the Numerical or External IDs, I get nothing even with hidden files enabled.

Can anybody provide any recommendations here? I can always provide any additional info. Should I also post in the MS forums?

There's so much data on these drives that I cannot loose.

Regards, Jimmy

 

Can't unlock Bitlocker Encrypted Drive

I have a Bitlocker encrypted external HDD without any OS installed in it. I plugged it to pc with usb then i unlocked my drive on Win10 with my password as usual then i was copying the data from my unlocked
Bitlocker encrypted drive to another non-encrypted drive. Then power cut suddenly. After that i can't access my Bitlocker encrypted drive anymore.

-When i try to unlock that drive from Windows Explorer pop-up says "Encryption on this drive is not compatible with your Windows. Try to unlock it with newer version of Windows." without password and recoverypassword/recoverykey
input options. But my Win10 is fully updated (1703)

-Tried Win7 popup came without asking any password "Failed to unlock the drive. No protector keys found in this drive."

-I also tried manage-bde -bitlockerdrive -protectors -get the output is "ERROR: No key protectors found". But drive seems like encrypted already.

-I tried repair-bde with 48 digits recovery password for recovering data to another HDD. Recovery done without any errors. Then did "chkdsk
outputdrive: /f" it says "File system is NTFS. The first NTFS boot sector is unreadable or corrupt. Reading second NTFS boot sector instead. Unable to determine volume version and state. CHKDSK aborted." The disk shown as RAW and i can't access it.

-After that i also tried thirdparty recovery tools for recovering data on the drive that created after repair-bde (decrypted RAW one). I recovered all my files without any corruption. But all of them shown
as RAW files and had randomized names without folder structure. Somehow repair-bde can't transfer folder structure. I tried thirdparty recovery tools on unaccessable Bitlocker encrypted drive. It listed all my files with correct file names and folders. So
folder structure on encrypted drive is not corrupted i think but i can't recover them because they are encrypted and i can't open any file. I need folder structure, my files are too dispersed. What is the solution ? Thanks.

 

Failure to unlock BitLocker encrypted HD after new windows 10 installation

Hello Kostas,

Thank you for bringing up your query on Microsoft Community.

We sincerely regret for the inconvenience caused.

You can use BitLocker Drive Encryption to help protect your
operating system drive (the drive where Windows is installed), a
fixed data drive (such as an internal hard drive), or a
removable data drive (such as a USB flash drive).

The way you unlock an encrypted drive depends on two things:

• What kind of drive it is.
• What kind of unlock method you chose when you set up BitLocker on the drive.
  

I suggest you to refer to the following article and check if it helps.
