Bitlocker is inaccessible; says Cannot use RecoveryKey to unlock... Try differant key RRS feed

  • Question

  • Yesterday during a client meeting (distraction), I attempted to place the laptop into sleep mode but it just HUNG. So I did a "Hard Power Off". Later after restarting, the Bitlocker icon was missing on encrypted 1Tb Data Drive E: (only encrypted drive) C:WINDOWS and D:PROGRAMS not encrypted            (approx 55% free space on E:)

    After reading and research I tried to access using CMD (admin) using manage-bde -unlock E: -recoverypassword 'CORRECT RECOVERYKEY ETC'   
    and I get      ERROR: The password failed to unlock volume E: 

    I KNOW it is the CORRECT RECOVERY KEY (it was saved on my MS acct)

    So I tried:  C:\>repair-bde E: F: -rp 'CORRECT PASSWORDKEY  665808-164791' ... 
    RESULTS:

    Scanning boot sectors for pointer to metadata:   1%
    LOG ERROR: 0xc0000033
    Failed to authenticate using supplied recovery information. (0x80310027)

    Then:

    LOG ERROR: 0xc0000033

    Scanning sector boundaries for metadata: 100%
    Finished scanning for BitLocker metadata.
    Then at the end of the scan: 
    ERROR: Cannot use '665808-164791 .... ' to unlock the input volume. Please try a different recovery password, recovery key
    or password.

    Current Status of Drive E:

    C:\WINDOWS\system32>manage-bde -status E:
    BitLocker Drive Encryption: Configuration Tool version 10.0.14393
    Copyright (C) 2013 Microsoft Corporation. All rights reserved.

    Volume E: [Label Unknown]
    [Data Volume]

        Size:                 Unknown GB
        BitLocker Version:    2.0
        Conversion Status:    Unknown
        Percentage Encrypted: Unknown%
        Encryption Method:    XTS-AES 128
        Protection Status:    Unknown
        Lock Status:          Locked
        Identification Field: Unknown
        Automatic Unlock:     Disabled
        Key Protectors:
            Password
            Numerical Password

    So... 

    Can I use the "-changepassword" command and use the new PW?   Then rerun scan using "NEW PW"? 

    Did I corrupt something on the drive?
    What is wrong and how to fix please ... is my important data at risk?

    Thank you For ANY resolve!

  • Hi AREA1031,

    It seems that you didn`t use the correct recovery key. Please run "manage-bde -protectors -get c:" then compare the key identifier to ensure you are using the right key.

    Best regards

  • If the key is indeed correct (verification: see MeipoXu's command, but use the correct letter: manage-bde -protectors -get e:), then something is badly corrupted and you'll need to restore your important data from your backup.
