Hi, I just got a new external HD. I'm using it as a time machine so it's backing up 150GB now. It's 1TB so that will leave about 770GB...so once the backing ups done should I create a partition for like regular storage? My startup disk in my Macbook is full, so maybe set the time machine partition at 175GB and then set the other partition for the rest of the space? Is that right? Thanks in advance!
