I have an external hard drive that was encrypted with BitLocker on an earlier version of Windows 10 Pro. After upgrading to the latest version of Windows 10, I am no longer able to access the drive using my previous password. When I try to unlock it, I receive one of two errors: "The password entered is incorrect" or "The key doesn't match this drive." I am pretty sure both the password and the recovery key are correct. The drive contains a large number of important files, so this is a major problem for me. How can I unlock this drive?
BitLocker is a popular full-disk encryption scheme employed in all versions of Windows (but not in every edition) since Windows Vista. It can help us protect data security, but it can also bring us disaster, such as losing both the password and recovery key can cause us to lose data forever. We should avoid this, but sometimes we are unable to unlock BitLocker drive even if we have the correct password or recovery key, and we get the "the password entered is incorrect." or "The Key doesn't match this drive." errors when trying to unlock the device. In fact, this problem may be caused by a BUG in the Windows operating system itself, and of course we can't rule out other reasons.
In this tutorial, we offer you two solutions to solve 'Unable to unlock BitLocker drive with correct password or recovery key' problem.
1. Connect the drive to a computer running a different version of Windows. If you clearly remember the Windows version used during encryption, you can reinstall that version directly.
2. In File Explorer, try to unlock the drive using the password or recovery key.
If you are still unable to unlock the BitLocker-encrypted drive with the correct password or recovery key, proceed to Solution 2 to unlock the drive and recover your data.
Download, install, and run Hasleo Data Recovery. On the main interface, you'll see several recovery options. Please select BitLocker Data Recovery mode.
1. Please select the drive where you lost files, then click "Scan" to find all BitLocker-encrypted partitions on the device.
2. A pop-up window will appear asking you to enter the BitLocker password or 48-digit BitLocker recovery key. If you don't want to enter the password or BitLocker recovery key here, just click the "Skip" button to skip it.
3. Hasleo Data Recovery will display all detected BitLocker-encrypted partitions on the target device. If you provided the password or BitLocker recovery key in the previous step, the password status will show whether they match the partition.
4. Double-click the partition you want to recover data from. If you've already entered the password or BitLocker recovery key and the password or recovery key matches, Hasleo Data Recovery will start scanning lost files. Otherwise, a prompt will appear asking for your BitLocker password or 48-digit recovery key. After entering the correct credentials and clicking "OK", the scan will start.
After scanning, the software will display a list of found files. You can preview them by browsing their paths or types. Select the files you wish to recover, then click the "Recover" button to save them to a destination of your choice. If your desired files are not found, click "Deep Scan" to initiate the Deep Scan Recovery process. This process takes additional time but can recover many more lost files.
To summarize, this tutorial introduced two solutions to resolve the "Unable to unlock BitLocker drive" issue. For cases where the correct password or recovery key is rejected, Hasleo Data Recovery—professional BitLocker data recovery software—can help you recover your data efficiently.
