So up to now, I've been encrypting all our laptops with TrueCrypt. Yesterday I received a new laptop that has a GUID partition table, which as you know is not a new technology. However, TrueCrypt only supports MBR partition tables, which means that I cannot encrypt this drive.
So, what are you all using to encrypt your drives that have GPT? No, this isn't Windows 7 Ultimate, and that is not an option. Also, no, I cannot delete and recreate the partition with an MBR partition.
