I have the following command running for 20 hours before I killed it: cryptsetup -v --verify-passphrase luksFormat /dev/sda8 Where /dev/sda8 is a 30GB partition. And during the time this command was running, it was using 100% of the CPU. How long does this "format" operation takes, usually, for a 30G partition?? echo. --------------------------------- Park yourself in front of a world of choices in alternative vehicles.
