![]() Note: If the BitLocker-protected volume is currently unlocked, we recommend copying any important data to a new volume before performing any of the following procedures. Data corruption can be caused by hardware failure or physical damage. In order to successfully unlock volumes protected with BitLocker Drive Encryption, BitLocker must be able to successfully read information about the volume and the encryption stored on the volume itself, called “volume metadata.” Although data corruption can occur, it is rare. Restart the computer and recover or repair the volume Metadata initial read: Primary metadata record on volume %2 could not be found. The filter driver writes event log information when it encounters problems, even if the problem is corrected with an automatic retry of the operation. Whenever the operating system or an application attempts to read from or write to a BitLocker-protected volume, the BitLocker filter driver must decrypt or encrypt data in real time, sector by sector.

The most recent recovery session happened because volume information could not be correctly retrieved from the volume metadata.Īlthough data corruption can occur, it is rare. If the user can supply a recovery password or insert a USB flash drive with a recovery key, BitLocker will unlock the volume.Īfter the Windows operating system volume has been successfully unlocked, BitLocker uses encrypted information stored in the volume metadata and Windows registry to unlock any data volumes configured for automatic unlocking.Įncrypted volume check: Volume information on %2 cannot be read.īitLocker entered recovery, and a user has successfully completed the recovery process by using a recovery key (stored on a USB flash drive) or a recovery password (entered manually at the recovery screen). If Windows cannot unlock the Windows operating system volume, BitLocker enters recovery mode. Success depends on the availability of configured key protectors, such as the TPM or a user-supplied PIN, and the existence of volume metadata stored within the encrypted drive. When a computer protected with BitLocker Drive Encryption is restarted, the early startup components perform a series of integrity checks and, if the system passes, attempts to retrieve the needed key information to unlock any BitLocker-protected volumes. Symantec Encryption Desktop 10.3.2 is the version installed on this hard drive. Is it possible to retrieve the keys from this unbootable hard drive and import these key into another copy of Symantec Encryption Desktop?
