The message indicates that BitLocker still considers the drive locked and is preventing the operation being attempted. Use the appropriate BitLocker unlock command for the drive and key type, then try access again.
If using Command Prompt with a recovery key (48‑digit numerical password), the syntax is:
manage-bde.exe -unlock D: -recoverypassword xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx
Replace D: with the correct drive letter and paste the full 48‑digit recovery password in the same format.
If using PowerShell, the equivalent is:
Unlock-BitLocker -MountPoint D: -RecoveryPassword xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx
If using a password instead of a recovery password in PowerShell:
$SecureString = ConvertTo-SecureString "YourPasswordHere" -AsPlainText -Force
Unlock-BitLocker -MountPoint D: -Password $SecureString
Alternatively, unlock from Control Panel/Explorer:
- Open Control Panel → BitLocker Drive Encryption.
- Find the locked drive and select Unlock drive.
- Enter the 48‑digit recovery key when prompted.
If the drive is damaged and cannot be unlocked normally but the recovery key is available, data may be copied to another drive using repair-bde (note this overwrites the target drive completely):
repair-bde C: E: -rp xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx
Here C: is the encrypted volume and E: is an empty target volume that will be fully overwritten.
