Has your hard disk ever become inaccessible after unlocking with BitLocker? Maybe your BitLocker password has been forgotten or the recovery key has been lost? Recently, I followed this tutorial to lock a drive with BitLocker on my system. After the tutorial, I kept the recovery key as an important consideration. Everything went well, but the problem occurred when I accidentally interrupted the process when the BitLocker blocked my hard drive.

The problem became more complex when I tried to access the drive data.

I received the following error message:

Drive location not available. Access denied

BitLocker Repair Tool

If your BitLocker password is forgotten or the recovery key is lost, you can use BitLocker Repair Tool to access data and files from an inaccessible BitLocker drive encrypted with BitLocker in Windows 10/8/7.

The BitLocker Repair Tool (Repair-bde) is a command line tool included in Windows 10/8/7. This tool can be used to access encrypted data on a severely damaged hard disk when the disk is encrypted with BitLocker Drive Encryption. It is particularly used to extract data from BitLocker drives that are sublocked BitLocker.

According to Technet, here is what to do. First make sure that:

  • Your test computer has a reader protected by BitLocker (even if the readers are locked).
  • They must be able to provide administrative evidence.
  • They must meet at least one of the following requirements :
              1. Recovery key file location
              2. Recovery key file location
              3. Recovery package file location and corresponding recovery password
              4. Recovery package file location and corresponding recovery key file location
        • You must have an empty output volume, which is equal to or greater than the drive protected by BitLocker (whose contents will be completely overwritten after repair).

Assumptions : Remember that we are talking about reader E: reader. We need to recover the data and extract it to drive F:. We have a 48-digit recovery password, for example 062612-026103-175593-225830-027357-086526-362263-513414 We also assume we have the recovery key file under F:RecoveryKey.bek and the recovery package under F:ExportedKeyPackage.

You must modify the above assumptions based on your environment.

Now open the command prompt (16) and execute one of the commands according to the recovery data you have.

Repair with recovery password:

Repair-bde E : F : rp 062612-026103-175593-225830-027357-086526-362263-513414

Recovery key repair :

 Repair-bde E : F : -rk F:RecoveryKey. bek

Repair with a recovery package and corresponding recovery password :

 repair-bde E : F : -kp F : ExportedKeyPackage -rp 062612-026103-175593-225830-027357-086526-362263-513414

Repair with a recovery package and corresponding recovery key :

 repair-bde E : F : -kp F : -kp F:ExportedKeyPackage -rk F:RecoveryKeyPackage. bek

When BitLocker checks the command you enter, the data is copied from the encrypted volume to the output volume (in our case F : drive). For example, when a drive is locked with BitLocker, data is recovered.

I hope you find this article useful.
