Problem with decryption / unlock Bitlocker external hard drive with correct password RRS feed

  • Question

  • I have external hard drive 2 TB with Bitlocker. I began decrypting, but I stop it on 4,2%. Later I safely disconnect it from system. When I connect it next time to the port and I tried to unlock with correct passport, the system information was, that password is not correct. How can I repair it, unlock or decrypt if it not working? I just used manage-bde -status command. I don't have recovery key.

    C:\WINDOWS\system32>manage-bde -status

  • The password is just as good as the recovery key. If it does not work, then the disk is corrupted. In that case, you need your backup now. Only forensic data experts can restore the already-decrypted parts (and will demand a lot of money to do so).

  • But why is corrupted? I stopped decrypting correctly and I remove it safely. It is any chance to repair unlocking device without data experts?

  • That cannot be answered. Pausing decryption is a supported procedure, as is shutting down a system while it's being decrypted. Pausing (stopping?) decryption and then ejecting a drive is, well, rarely done, maybe it's not possible and should have issued a warning. However, if the password does not work, there's nothing you can do. You could try 3rd party tools, but if the data is really important but you have no backup, I would recommend to ask forensic experts.
