cb911, I do have the 60GB IBM Travelstar drive that I pulled from my Rev. A TiBook. I installed it when I got home on Friday, but upon booting into OS X, I got a kernal panic. After a few of those, I put the 40GB drive that shipped with it back in. Once I did that, the panic went away. I'm thinking about putting the drive in again, and booting up with the OS X install cd that came with the new TiBook. Maybe that will make it work correctly, and not panic. I would like to do that, since I have email on the old drive that I would like to access again. I believe that I have succeeded in pulling my latest AIM buddy list back into Fire, but will have to check that tonight (from home). If I can get the old email back, I will keep the 40GB drive inside the new TiBook and make the 60GB drive external (firewire). I will probably get the enclosure before the end of next week, and have a total of 170GB inside and outside of the laptop. 😀
