Hi, I'm replacing my friend's hard drive in her Macbook. I threw in a SATA drive I had laying around but the Leopard Installer does not recognize it. I have it formatted to HFS+ and the hard drive mounts if I plug it via USB into my computer. The drive won't even show up in Disk Utility off when in her Macbook. Any advice? Does it need to be formatted in a different variant of HFS+? Maybe I haven't pushed it in enough?
