Summary: If you’ve accidentally formatted a BitLocker-encrypted hard drive, this blog will guide you on how to recover data from a formatted BitLocker-encrypted hard drive. You can use Stellar Data Recovery Professional software to recover deleted data or missing partitions from BitLocker-encrypted hard drives.
Microsoft offers BitLocker encryption feature for Windows to encrypt entire volumes, thus protecting data from unauthorized access. When you enable BitLocker on a hard disk, USB flash drive, or SD card, it encodes the files and folders stored on the device.
At times, you format the encrypted hard drive, resulting in data loss. Once you’ve formatted the hard drive, recovering the erased data could be difficult. In this post, we’ll be sharing the solutions to recover data from formatted BitLocker encrypted hard drive.
Reasons for Formatting BitLocker-Encrypted Hard Drive
Some possible reasons for formatting BitLocker-encrypted hard drives include:
Accidental Formatting: At times, while trying to format some other disk, you may end up formatting the disk containing important data.
Intentional Formatting: If the file system on a drive has turned RAW, you lose access to the data. In such a situation, formatting the disk is the only solution. But formatting may lead to loss of data.
Virus Attack: If your hard disk has been attacked by a virus, the data in the hard disk may get damaged or become inaccessible. In this situation, the computer’s antivirus or firewall may block the disk and force you to format it. In such cases, the Windows firewall may remove BitLocker’s metadata, resulting in data loss.
Methods to Decrypt BitLocker-Encrypted Hard Drive
Here are the methods to disable BitLocker encryption:
Method 1: Using BitLocker Drive Encryption Feature
Follow these steps to decrypt BitLocker-encrypted drive:
Go to the Start button.
Select Control Panel.

Select BitLocker Drive Encryption.
Click Decrypt Drive. (This option automatically unlocks the selected drive.)
Method 2: Decrypt using Certificates
To decrypt BitLocker-encrypted drive by using certificates, follow these steps:
[Note: For this, you need the certificate for the encrypted hard drive.]
Go to Start.
Type certmgr.msc and hit Enter.
Click and open Certificate Manager.
Choose a Personal Folder.
Choose Action > All Tasks >
Follow the Certificate Import Wizard and on-screen guidance.
Method 3: Using Windows GUI Mode

Look for the BitLocker-encrypted drive and click Turn Off BitLocker.
A message will be displayed stating that the drive will be decrypted and that decryption may take some time. Click Turn off BitLocker/Decrypt the drive to continue and turn off BitLocker on the drive.
This process may take some time to decrypt the drive and remove BitLocker protection.
Method 4: Decrypt via Windows PowerShell Mode
To disable BitLocker encryption via Windows PowerShell mode, Windows PowerShell must be installed on your system. If it isn’t, download and install the supported Windows PowerShell version from the Microsoft website. Then, follow the given steps:
[Note: If the partition with the operating system contains any automatic unlocking keys, the cmdlet to disable BitLocker encryption won’t work. Use the Clear-BitLockerAutoUnlock cmdlet in the PowerShell window to remove all automatic unlocking keys to disable BitLocker for the partition.]
Launch PowerShell in administrator mode.
Execute the following commands:
PS C:\>$BLV = Get-BitLockerVolume
PS C:\>Disable-BitLocker -MountPoint $BLV
Verify that the decryption is in progress through the following commands:
Execute the command: PS C:\> Get-BitLockerVolume
Check decryption progress in “Volume Status” and “Encryption Percentage”
