    I finally got the drive unlocked !!! -- After install all windows 10 update patches!!

    This might be a bug in certain version of windows 10.

    1. If you have an OS (Windows 10, Pro, x64 -- I might be able to find the exact version number of it later) which installed all windows 10 updates  -> Encrypt your drive using bitlocker 

    2. Reinstall OS  -- Your drive will NOT unlock even you have correct password or recovery key (just like above scenario I have).

    You have to install certain windows 10 update patch (I don't know which one I got), then it just unlock as it should be.

    The Microsoft guys in this forums even didn't asking what version of bitlocker I was using.

  • Hi,

    I have received the message regarding to your issue. Do you lock your system drive or the data drive? I suppose you do not unlock the drive before reinstall system. It is strange that the recovery key is not matched if this is the correct key.

    Firstly, we would like to know if you have the BitLocker feature in your new system and enable it. Please enable this feature if you haven't.

    We would like to suggest you could use the PowerShell command in the link below to restore the access to the drive.

    https://technet.microsoft.com/en-us/library/jj649833%28v=wps.630%29.aspx?f=255&MSPPError=-2147217396

    Please Note: Although the link above it applied to Windows 8, you could give it a try.

    Hope that will be helpful to you.

    Best Regards

    Simon

  • Hi Simon, 

    1. My system drive didn't lock, I only locked my data drive (it's a separate hard disk with OS disk)

    2. Yes, I didn't unlock my data drive before reinstall OS -- I believe it's not required to do that right.

    3. I took the locked drive out, and tried it on 4 different computer/ laptop which have BitLocker feature enabled in those systems.

    I tried the link - still not work.

    The problem is that: seems like this locked drive does not recognize my password, and the 48 digit recovery key ( I am petty sure the password correct, and the 48 digit recovery key DOES match for this drive -- see my screen shot above)

    Thanks,

  • When you encrypt fixed data drives, you can choose to have the drive automatically unlock when you log on to Windows.

    Removable data drives can be set to automatically unlock after they are encrypted by right-clicking the drive in the Computer folder, and then clicking Manage BitLocker.

    Note

    • To be able to automatically unlock fixed data drives, the drive that Windows is installed on must also be encrypted by BitLocker.

  • Hi Carey 

    It's not about auto-unlock at all.

    I can't even unlock it. Please see my 1st post, I have tried 

    1. my password

    2. the 48 digit recovery key,

    That's all I have and have tried those password/keys. but still can't unlock my drive.


    I just want to get my data back.
    thanks

  • Hi,

    Thank you for your reply.

    I have tested for your issue. Lock the data volume and reinstall system without unlock it. After that, we do not encounter the issue as you mentioned.

    Therefore, we would consider there is something wrong with your drive hardware. You would better to contact the data recovery specialist to restore your data in the drive.

    Wish you have a nice day.

    Best Regards

    Simon

  • My guess is something goes wrong in the encryption:

    I just run a command, to check the status of the encrypted drive:

    manage-bde -status F:

    C:\WINDOWS\system32>manage-bde -status F:
    BitLocker Drive Encryption: Configuration Tool version 10.0.10011
    Copyright (C) 2013 Microsoft Corporation. All rights reserved.

    Volume F: [Label Unknown]
    [Data Volume]

        Size:                 Unknown GB
        BitLocker Version:    2.0
        Conversion Status:    Unknown
        Percentage Encrypted: Unknown%
    ERROR: An error occurred (code 0x80070057):
    The parameter is incorrect.

    Does this help anything?

  • Same problem as mine

    Actually I already disabled the bitlocker before  a Windows 10 update that happens after several weeks.

    The bitlocker automatically Turned ON by itself and now I cannot unlock it either using password or recovery key.

  • You may want to re-install windows 10 to the version which before windows update. then try to unlock your drive from there.

    Seems to me,  Different windows 10 versions using different algorithm to lock/unload the driving using the user type in  password/recoverykey.

  • "Seems to me,  Different windows 10 versions using different algorithm to lock" - as I wrote in your other thread: it's win10 v1511 that changed the game. 1511 uses AES-xtc as default and version pre 1511 cannot read that. Even with the correct key, they show "password incorrect".
