This tutorial will teach you how to recover deleted or lost files from an inaccessible BitLocker-encrypted drive, mainly covering the following aspects:
There are numerous causes that can result in a BitLocker-encrypted drive becoming inaccessible. The most common issues include virus attacks, unexpected system shutdowns, and unsafe removal of USB drives. The root cause is that the drive's file system gets corrupted, making it impossible for Windows to read the file structure properly. When you attempt to access such a drive, Windows will display the error message: "D:\ is not accessible. Access is denied". Many users assume all their files are permanently lost in this situation. In reality, the files are not gone — they still remain on the drive but are simply unrecognizable to Windows. Given that the files are still stored on the drive, using data recovery software to retrieve them is the correct approach. However, it is important to note that data recovery from an inaccessible BitLocker-encrypted drive is far more challenging than from a regular unencrypted drive. After testing multiple data recovery tools, you will find that most of them fail to recover data from inaccessible BitLocker-encrypted drives. This is because all data on the drive is protected by BitLocker encryption, and standard data recovery software does not support BitLocker decryption.
The answer lies in using professional BitLocker data recovery software. We recommend Hasleo BitLocker Data Recovery, a tool specifically designed to recover data from BitLocker-encrypted drives. It correctly parses encrypted data and displays found files in a clear file tree, allowing you to recover lost files as needed. The following tutorial provides step-by-step instructions.
1. Select the inaccessible BitLocker-encrypted drive, then click the "Scan" button to locate 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 list all found BitLocker encrypted partitions on the inaccessible device. If you have entered the password or BitLocker recovery key in the previous step, the password status will show whether the password or BitLocker recovery key matches this 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.

When the scanning process gets finished, you can filter and preview found files by path and file types. When you locate the files you want, just select them and click on "Recover" button to save them to your hard drive or other storage device. If some files are not found, please click "Deep Scan" button to start the Deep Scan Recovery process, deep scan takes more time, but can find much more lost files.
