I owned an HP laptop before. I had bought a Seagate Backup Plus Drive to transfer all my videos and images etc into that from my computer. Now i own a MacBook Pro. I just connected the backup drive to my mac and I see that i can't edit it, i can't make a new folder! Pls help! Im not even good with technology all that well so i would love it if you could explain in simple language hehe. Thanks!
