When you enable BitLocker on a hard disk, USB flash drive, or SD card, Microsoft Windows encodes the files and folders stored on the device so that only the permitted users can access the data. But sometimes, you might need to remove BitLocker encryption to access or open the encrypted drive. To do this, you have to erase or format the encrypted hard drive. There are several methods to do so. But once you’ve formatted it, recovering the erased data could be difficult. If you can’t afford to lose your important data, we have data recovery solutions for you. You can follow the methods but let’s discuss the possible reasons for formatting first.

Reasons for formatting BitLocker Encrypted Hard Drive

There could be many possible reasons to get the BitLocker encrypted hard disk formatted. These reasons and recovery methods are discussed underneath.

  • Accidental Formatting: People might format their hard disks mistakenly. They might’ve been trying to format some other disk but end up formatting the disk that contains their important data and realize the mistake when it’s too late.
  • Intentional Formatting: People may be unable to access their drive in case its file system has turned RAW. In such a situation, people usually format their disks to access the hard drive, but their data is lost as a result of formatting.
  • Virus attack: If your hard disk has been attacked by a virus, the data within your hard disk will also be damaged and might become unreadable. In this condition, your computer’s antivirus or firewall might block the disk and force you to format it. In such cases, the Windows firewall might remove the BitLocker’s metadata thereby resulting in data loss.

Here’s a sample process Stellar Data Recovery follows to extract lost data from formatted BitLocker encrypted hard drive:

    1. First, the drive is examined to confirm if it is in working condition
    2. Then an image of the hard drive is taken in case it has bad sectors
    3. Thereafter, the BitLocker password is entered to decrypt the drive
    4. Next, a scan of the drive partitions is carried out to fix the errors by using Stellar Data Recovery’s proprietary tools and software. The detailed process is explained below in the blog.
    5. After this, each file and folder of the drive becomes accessible and is opened to check for anomalies.

Note: Key/password is required to unlock the drive for data recovery

Ways to decrypt BitLocker encrypted hard drive

BitLocker encryption can be disabled in two ways:

Through Windows GUI

  1. Log in with administrator credentials
  2. Click on Start -> Control Panel -> System and Security -> BitLocker Drive Encryption
  3. Look for the drive on which you want BitLocker Drive Encryption turned off, and click on Turn Off BitLocker
  4. 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

It might take some time to decrypt the drive and remove BitLocker protection.

Through Windows PowerShell

You must have Windows PowerShell installed for this.

Note: If the partition with the operating system contains any automatic unlocking keys, the cmdlet to disable BitLocker encryption won’t work. You can use the Clear-BitLockerAutoUnlock cmdlet in PowerShell window to remove all automatic unlocking keys to disable BitLocker for the partition.

  1. Launch PowerShell in administrator mode
  2. Execute the following commands:
    1. PS C:\>$BLV = Get-BitLockerVolume
    2. PS C:\>Disable-BitLocker -MountPoint $BLV
  3. Verify that the decryption is on way through the following commands:
    1. Execute the command: PS C:\> Get-BitLockerVolume
    2. Check decryption progress in “Volume Status” “Encryption Percentage”
