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?

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.
