The new TrueCrypt 5.1 version finally enables hibernation with pre-boot authentication. I am going to try it out as soon as possible. A big thank you to all the developers!
Update 2008-03-16: Today I finally had time to test out pre-boot authentication. It simply worked great. No problems at all. As I was using it on a notebook, I was very happy about the possibility to interrupt and resume the encryption process.

After quite some time, a new version of my favorite encryption tool is out: TrueCrypt developers have released version 5 of their product, introducing a new killer feature (among others): System Volume Encryption with pre-boot authentification (only Windows 2000/XP/Vista). This means, that TrueCrypt will encrypt everything on your system drive, including page- and hibernation file,
finally making hibernation a safe and easy possibility.
I am going to look into this next week, as I need my notebook on Saturday (just in case anything goes wrong).
Update 2007-02-08: As my first commenter below points out, it seems hibernation is disabled by TrueCrypt while having your system partition encrypted. I don’t really understand why at the moment, but I will investigate further. For me this is a primary show-stopper, as this was the long-awaited functionality I was waiting for.
Nitpickers Corner¹: Of course I am aware why encryption and hibernation in general are no-goes together, but I don’t understand why this is an issue when full-system encryption is enabled.
Update 2007-02-08 (again): Ok, in this TrueCrypt forum thread they explain why they cannot support it at the moment: Windows treats the hibernation file differently, it seems to bypass the TrueCrypt driver and therefore would still write keys to disk without encryption. Ok, still get to wait for my dream feature then, but I still refuse to buy PGP 🙂 Thanks to the developers for their great work anyhow!
