A noob question: I am currently running Snow Leopard on my Macbook. My hdd was failing so I bought a 1TB hdd to replace my old one. I used a hdd clone device that's intuitive and automatically clones the old one. Everything went well. The new drive boots however, when I look a the Mac.. hd it shows the old hdd size...Even though I have a full 1TB as the new HD. Is there anyway I can extend the size of the hd? I've attempted to pull it down to make it larger but to no avail... I've attached a picture from Disk Utility if it's useful.
