It has taken about 2 days to encrypt my 4TB drive with about 2TB of contents in it. Is this normal? While I know its okay to unplug it and let it resume encrypting at its own leisure everytime I use it I want to know if it really takes this long for a 4TB drive. I am checking the progress by the command line "diskutil cs list". It says it has encrypted 3.8TB out of 4TB and the status is not fully secure but it does ask for a passcode when I plug it in if I eject it and works normally otherwise.
