    How to Unlock a Drive using BitLocker Recovery in Windows 8 and 8.1


    information   Information
    There are several reasons that might make a PC go into recovery mode. For example, your organization might have a password security policy that locks you out after a certain number of failed attempts to sign in. Or perhaps your PC encountered a hardware malfunction, an unexpected configuration change, or another security event. Requiring a recovery key helps ensure that only an authorized person can unlock your PC and restore access to your encrypted data.

    This tutorial will show you how to use BitLocker recovery to unlock an encrypted OS drive, fixed data drive, and removable data drive in Windows 8 when you are not able to do so normally say using the password or USB flash drive.

    Tip   Tip
    If you were signed in to your Microsoft account when you encrypted a drive with BitLocker, then you can get your recovery key from your OneDrive at the link below.

    7. If you Saved the Recovery Key to a File or USB Flash Drive

    warning   Warning
    Only choose this option as a last resort because it will delete your personal data from the PC. While BitLocker helps protect your data against unauthorized access, it also prevents you from ever accessing your data again if you are unable to unlock it.

    Windows 10 bitlocker protected drive is not working.


    Hi,
    Shawn,

    I appreciate your effort. Your post is really helping me out. I am applying 3rd method. The following error came up.
    Click image for larger version

    This is my case history:

    I have Windows 10 and BitLocker enabled.

    HDD, Seagate 3TB, partitioned into 5 drives.

    I did this mistake, I created a bootable USB by easy bcd and tested on host window during boot. Reached to the point where windows setup asks for disk selection, I clicked on the drive(setup says drive encrypted and can't continue) but didn't go further.

    Then I boot nothing shows up.

    Tried to connect 3tb hard to another PC to unlock drive but it's not accepting the correct password and recovery key.

    I made windows image before encryption. After restoring that 2nd and 4th drives are not accessible, 5th is formatted and 3rd drive data is intact with minor data loss.

    I ran testdisk-7.0 and found no drive in the quick search. The log file is pasted below.

    Hi,
    Brink,

    On given link, the drive shows BitLocker encryption sign but in my case not.

    I tried cmd recovery before but no luck.

    Here you can see my drives status in the screenshot.

    Jillian,

    The drives's icons don't indicate that they are encrypted by BitLocker in that screenshot. Are you able to open them now?

    I am not able to open them. Before the issue bitlocker logo was visible.

    My drive is not capable of h/w encryption. Here is its model
    ST3000DM001.


    Can TPM effect non-OS drives?

    Thanks.

    What happens when you try to open them? Any error messages?

    For now, it wouldn't hurt to double check their BitLocker status using the tutorial below.

    BitLocker Status - Check for Drive in Windows

    If you have a TPM, it can be used to unlock or decrypt BitLocker for only a OS drive.

    It says you need to format that drive before use.

    I repaired Bitlocker using the following command


    repair-bde H: J: -rp KEY -f -lf I:\log.txt


    The following errors showed up

    The log is showing that it failed to decrypt data at several offsets on the drive.

    I hate to say it, but it looks like the data has been permanently loss.

    You should be able to format the hard drive to be able to use it again, but the data will be gone.

    Do you have backups of the data?

    Not backup type data.

    But I want to learn any solution if possible. If it happens to valuable data then I definitely need it.
