Coming from TrueCrypt on W7 I have a few questions about disk encryption in Lion. 1. Is it possible to change the password without reencrypting the whole disk (I realize it is not as safe, but I've used this several times before on non-cruical data as it saves a lot of time)? 2. I read that it is possible to encrypt external (USB) hard drives. How does it work in reality? Does the system automount the encrypted external drives on login (if the password is the same as for the system disk)? 3. Is it still possible to use Truecrypt for encrypting non-system hard disks? Is it true, that upon startup, Lion always offers to format Truecrypt encrypted hard disks as they are not recognized? Is it possible to disable these notifications? Thanks!
