Hi I just wanted to let people know about an experience I had the other day. After using my Powerbook G4 for about 4 years with some files encrypted with File Vault my Mac suddenly refused to let me log into my user account. I took the Mac to an authorized Apple repairer and was told that a file in File Vault had become corrupted and infected the rest of my hard drive. I lost all my files and documents, photos, music - the lot. When it happens, all you get from Apple is "Sorry about that, but there is nothing we can do - You should have backed up all your files". I'd just like to warn people not to use File Vault.
