Hi all. I'm looking to replace the HDD in my sister's late 2006 Macbook. Her existing 80GB is almost full with less than 1GB free space remaining. I'm looking at replacing it with a Seagate 7200.3. Physically replacing the drive is fine but what do I need in order to copy everything over to the new HDD? I know I could just use the boot disk that came with her Macbook (which was Tiger, if I'm not mistaken) but I have a lot of programs that she's installed that she apparently lost the install discs for, such as Leopard. If it makes any difference, she does have Time Machine back-ups along with a 1TB external to use, if needed. Thanks!
