A friend has an older black MacBook with the Core Duo processor; he bought a new SSD and we formatted it externally, then installed it and tried to run the Leopard installer via DVD. No matter what I try, the Leopard installer won't "see" the SSD drive. If I boot-up from an external disk that has Leopard already installed, it can see that the SSD is in the MB and everything is fine, but when running the installer it stops seeing it. I've reformatted it a few times on other computers, but when I try to run Disk Utility and Terminal inside the installer DVD, they can't see see the internal SSD either. What's weird is that he was even able to install Tiger on the SSD from the Tiger DVD, but when he tried to do an upgrade within the OS, it wouldn't show the SSD. Also, Leopard installed on the MB fine via an old Toshiba drive, but it just won't see the SSD. In other words, I've tried every possible configuration to make sure that Leopard can work on the older MB, and to make sure that the hardware is able to recognize the internal SSD. It just seems to be an issue with the Leopard DVD. Any ideas?
