2018-5-12, Posted by Jerry to BitLocker Data Recovery

On my old computer, there is a data partition on the main disk was encrypted with BitLocker Encryption, and I forgot the password because I haven't used the computer for a long time. I looked at a lot of possible ways to get my password back, but none of them helped me solve the issue. My question is how to recover lost data after you lose or forget your BitLocker password?

We need to remember a variety of different types of passwords, bank card passwords, mail passwords, computer user passwords and disk encryption passwords (BitLocker password), and so on, but for security reasons, we have to regularly modify the various passwords, so we always forget the password. If we lose or forgot the BitLocker password for a BitLocker encrypted partition, you can try the following solution to access your lost data.

 

Solution 1: Unlock Bitlocker encrypted drive with 48-digit BitLocker recovery key.

After that, you can right click on the drive letter in Windows Explorer, then select "Change BitLocker Password" from right-click menu, and then modify the password in the pop-up window.

If you cannot find the recovery password, please refer to What is BitLocker recovery key and how to find BitLocker recovery key?

Please note that:
1. You must enter the correct Bitlocker password or the 48-digits Bitlocker recovery key to successfully recover data from a BitLocker encrypted drive.
2. If the metadata area of a BitLocker encrypted drive is severely corrupted, you will not be able to recover data from this partition even if you have the correct Bitlocker password or the 48-digits Bitlocker recovery key.
3. Don't save the recovered files to the partition where your lost files originally located. This prevents your data from geting overwriten.
4. You can export/save the scanning results for later or next recovery.
