After creating the Bitlocker Management package for Symantec Endpoint Encryption 11.1 and installing it on an endpoint, the endpoint does not encrypt.
Bitlocker requires a small additional partition that it will use to store encryption data. If the drive is not appropriately configured, it will not encrypt.
There is a built-in Microsoft Bitlocker configuration tool which can be used on a system to repartition the drive appropriately for use with Bitlocker, bdehdcfg.exe. It shrinks the existing drive and creates a new partition, and should not result in data loss under normal operation. An example command to resize/repartition the drive to work with Bitlocker is as follows: bdehdcfg.exe -target default
This command should be run through an Administrator Command Prompt. The -quiet flag can be appended to make this process invisible to the user as follows: bdehdcfg.exe -target default -quiet
This command can be issued either before or after Symantec Endpoint Encryption is installed. After the drive is repartitioned via the tool, it should register a user and begin encryption on the next reboot. As it is a Microsoft tool, any issues encountered during the use of this tool should be directed to Microsoft.
