I need help with firevault and a external hard drive
I Just purchased a LaCie Porsche Design 2 TB external hard drive, I installed it successfully but my computer says the fire vault needs to encrypt the "Machintosh HD" disk before I can use Time Machine to back up my computer. It says it has more then one day remaining before the firevault finishes. Should I wait for the fire vault to finish and then use time machine or turn the fire vault completely off then back it up?
