Vista BitLocker Drive Encryption tips

Dana L. Brundage, Site Editor

BitLocker Drive Encryption is a full-drive encryption feature in Windows Vista, Microsoft's latest operating system. With BitLocker, your Windows PC or laptop cannot start up without an encryption key, helping to keep your computer safe if stolen. There are some hardware requirements necessary to use this function, including two partitions on your hard drive. However, contrary to popular belief, BitLocker can be used on a computer with or without a TPM.

"I think that being able to implement hardware level encryption against a laptop's hard drive is something that was long overdue," says Brien Posey, Microsoft MVP and SearchWindowsSecurity.com site expert. "BitLocker can only be used to encrypt a single drive, and in some cases that will be insufficient, for example, if a computer has two hard drives. I do expect this limitation to eventually go away though as the technology matures over the next few years. My only concern with BitLocker, though, is that I have heard some horror stories regarding data recovery on encrypted drives."
