Customizing Your VAIO Computer
Using BitLocker Drive Encryption with the TPM
BitLocker Drive Encryption is a data encryption feature that is available on models with Windows Vista Ultimate. Enabling
BitLocker Drive Encryption with the TPM encrypts all data on the C drive.
For detailed information on how to use and configure BitLocker Drive Encryption, see Windows Help and Support.
Notes on using BitLocker Drive Encryption
❑ Be sure to initialize the TPM with the Infineon TPM Professional Package before enabling BitLocker Drive Encryption.
If you enable it without initializing the TPM, a TPM owner password is not generated, so you will not be able to configure
the Infineon TPM Professional Package.
❑ The Infineon TPM Professional Package does not make a backup copy of a file (recovery password) for BitLocker
Drive Encryption.
❑ An additional BitLocker system partition (S drive) has been pre-configured. This system partition uses 1.5 GB of your total
hard disk drive volume.
❑ You must enable the TPM in the BIOS setup screen in order to turn on BitLocker Drive Encryption.
