First, there is a problem with creating a recovery CD. If you try to burn the image TC gives you with Alcohol 120% or PowerISO, it will not work. Alcohol burns it, but validation fails. PowerISO doesn't even want to burn that image. You have to use InfraRecorder that their website links to. I have no idea what they are doing with that image, but there is no reason why I should have to go out and get some other piece of software to do the same thing as Alcohol or PowerISO.
That's not the major problem though. So far, I could not encrypt my drive. The process goes to about 21% then dies with a "Data error (cyclic redundancy check)." Very descriptive, as you can tell. I just finished running checkdisk to see if this could be caused by bad disk sectors - nope. The hard drive is perfectly fine. I'm not the only one having the same problem. There are a number of people on wilderssecurity forums that have the same issue.
I have that 21% of the disk encrypted, and pre-boot authentication works fine... now if it could only work for the entire disk. The other thing I found out is that apparently encrypting your system drive will disable hibernation. Not a great thing for my laptop (Fujitsu P7010, in case you were interested). I could live without hibernation for a while, assuming that it will come eventually in a later release. The encryption problem is another story.
