How to Recover Data from a BitLocker-Encrypted Drive?

A BitLocker drive that won’t open can cause a lot of stress when the contents of the drive are extremely important. Maybe it’s the photos you kept telling yourself you’d back up eventually. Maybe there’s a contract due first thing tomorrow. Or maybe you just saved something in one place instead of two, until it comes back to bite in the form of data loss.

Encryption has exactly one job: keeping the wrong people out. That’s what it was built for, nothing more. It was never meant to protect you from a corrupted drive, a format you triggered by mistake, or Windows unable to read the disk anymore. These are the situations where users often find themselves without a clear path forward.

One thing stays constant through all of this: no password, no key, no recovery. This applies to every method available. No BitLocker recovery tool, or recovery service can break BitLocker encryption without proper credentials. This guide also covers how to find your BitLocker recovery key if it’s not available.

Which BitLocker Recovery Method is Right for You?

Choosing which BitLocker recovery method is right for you depends a lot on the type of encryption and whether there was any corruption, formatting, or RAW files involved. The following table compares all three options mentioned above to choose the best approach.

Note: Once TRIM has processed deleted data on an SSD, those files are permanently erased, not simply hidden. The same applies if the drive has been fully formatted or re-encrypted after access was lost. No recovery software can reverse this.

Method 1: Unlock the Drive with Your BitLocker Recovery Key

At times, a BitLocker-encrypted Windows drive stops taking your normal login, even when you type it perfectly ten times in a row. When this happens, you will be prompted to enter the BitLocker recovery key instead. Enter the right 48 digits, and the drive will become accessible again.

Steps to Unlock a BitLocker Drive with Recovery Key

• Open File Explorer and locate the drive displaying the BitLocker lock icon.
• Double-click the drive. The authentication dialog will appear.

• Enter the password. If you don’t have the password, use the link ‘I forgot my password’.
• Type in all 48 digits of the recovery key in the same order as they are listed in the records. Authentication will fail even if one digit is wrong.

• Click Unlock and wait until Windows is checking the key.
• The drive will now be visible in File Explorer, just as if it were any other drive.

Alternatively, for those who want to use the command line, an easier way to unlock the drive is from Windows by simply running the following command:

manage-bde -unlock X: -RecoveryPassword <48-digit-key>

Note: In the command below, X: is a placeholder. Replace it with the actual drive letter assigned to the locked drive. For example, if the drive appears as E:, use E: in place of X:.

The recovery password specified in the command is used to access BitLocker in Windows. Upon successful authentication, the drive is instantaneously accessible, and your files become available.

Don’t Have Your BitLocker Recovery Key? Here’s Where to Find It

Before attempting to recover Microsoft BitLocker, check the following locations for your BitLocker recovery key.

Check Your Microsoft Account

In numerous instances, the BitLocker recovery key is automatically backed up to a Microsoft account on personal Windows devices.

Visit: account.microsoft.com/devices/recoverykey

Multiple recovery credentials may be listed. The Key ID displayed should be compared to the Key ID displayed on the BitLocker activation interface. The appropriate key is identified by the corresponding ID.

Look for a Saved Text File

During setup, Windows may save the recovery key as a text file on the system. Search for files with names that include:

• BitLocker Recovery Key
• Recovery Key
• BitLocker Key

Open any matching file and verify the Key ID.

Check Printed Documents

Many users choose to print the recovery key during BitLocker setup.

Look through:

• Printed records
• Device setup paperwork
• IT documentation
• Personal file folders

Again, verify that the Key ID matches the one displayed by Windows.

Check a USB Drive

The BitLocker recovery key may have been stored on a USB flash drive. Search for text files that include recovery key details. Connect any USB drives that may have been used during the BitLocker setup process.

Check Microsoft Entra ID

The BitLocker recovery key may be stored in Microsoft Entra ID if the computer is owned by an organization, school, or workplace.

Students and employees can sign into their organizational accounts to check whether a recovery key is stored there.

Contact Your Company’s IT Administrator

BitLocker recovery information is centrally stored on corporate devices.

If the drive is owned by your organization, contact your IT department and provide them the Key ID seen on the recovery page. If the organization has the BitLocker recovery key on record, the IT department can retrieve and provide it.

And if that key is gone? Not just misplaced? Then the data stays locked, no workarounds. BitLocker does exactly what it was designed to do, which is not let anyone in without the key.

If the drive remains locked despite entering the correct key, proceed to Method 2.

Method 2: Repair a Severely Corrupted Drive with “repair-bde”

If the encrypted drive has sustained serious damage and standard tools such as decryption and scanning are unable to function, repair-bde is the appropriate utility to run. It attempts to recover whatever data remains accessible, even on severely damaged drives.

Before running repair-bde, make sure you have:

• A second empty drive with equal or larger capacity.
• The BitLocker recovery key, password, or .BEK key file.
• Administrative access to Windows.

Important: The process will result in the complete overwriting of the destination drive. All data that is currently stored on that drive will be deleted.

Using repair-bde

Open Command Prompt as Administrator and run:

repair-bde C: D: -rp <48-digit-key> -lf C:\log.txt

What Each Part Means

• C: = damaged BitLocker source drive
• D: = destination drive receiving recovered data
• -rp = specifies the recovery password
• <48-digit-key> = your BitLocker recovery key
• -lf C:\log.txt = creates a recovery log file

The repair-bde utility helps extract accessible data from the damaged BitLocker encrypted drive and transfer it to the destination drive.

However, it is important to understand its limitations.

• It cannot recover deleted files.
• It cannot restore files already overwritten.
• It cannot repair drives that failed during encryption or decryption.
• It salvages existing accessible data rather than rebuilding damaged files.

The BitLocker metadata of the drive may be obliterated in certain severe corruption cases. In such cases, the recovery key may not be sufficient. A key bundle, which is typically held in a company’s Active Directory environment, may also be necessary for the repair-bde utility. 

Method 3:Recover Data from a BitLocker Drive Using BitLocker Recovery Software

Still, don’t assume the worst too quickly. A drive that got formatted by accident, files missing after decryption, or a drive showing up as RAW doesn’t mean everything’s lost. Windows data recovery software can often retrieve your files, as long as you’ve got the right password or recovery key. This requirement applies regardless of the condition of the drive.

Stellar Data Recovery adheres to Microsoft’s BitLocker requirements throughout the recovery process, ensuring that all operations remain within the bounds of what is permitted. The drive is only scanned by the software after the necessary credentials have been entered.

Follow These Steps to Recover Data

• Start the program and choose the kind of file types to recover, such as data documents, photos, videos, or e-mail.

• Select BitLocker drive from the list of drives, and then click Scan.

• You will be prompted for the software to enter the password/recovery key. Type the password to access the system and start scanning.

• The software will check that drive for any files which were deleted, gone, or inaccessible.
• Preview the files before recovering them to be sure that the files you need are there.

• Select the files to recover and save them to a separate drive.

Important: It is imperative to save recovered files to an alternative storage device. Attempting to save them back to the source drive may result in the overwriting of recoverable data.

Files formatted using the quick format option on a BitLocker-encrypted disk may often be recovered. However, the chances of recovery are significantly lowered after a complete format or if the disk has been reformatted and encrypted again.

Even if the disk is inaccessible or RAW or has file system issues, the software may scan the drive after successful authentication for the BitLocker recovery key.

Why Use Stellar Data Recovery for BitLocker Recovery?

Stellar Data Recovery functions as a reliable BitLocker recovery software for recovering files from:

• Deleted BitLocker volumes
• Formatted BitLocker partitions
• RAW BitLocker drives
• Inaccessible BitLocker encrypted drives
• Missing files after unlocking a drive

Conclusion

The success of recovery depends upon which method you chose to unlock the drive, whether you have the correct password or recovery key, as well as on the condition of the drive. Valid credentials are necessary regardless of whether the objective is to unlock, recover files, recover the entire disk, or restore a severely corrupted drive. Once authenticated, the software will be able to retrieve all available data that was accidentally deleted, formatted, RAW, or missing.
