i got to do the boss a favor. one of my previous jobs was a DJ and i have a TON of karaoke music. he has a karaoke machine with a HDD, so i took it out and now I'm trying to load my music in it. problem is its a brand new HDD and i have a mac. I've never done this before but do i need to format it? how do i do that? I'm plugging in the drive via usb and its not recognizing it. halp plz
