Hello, I had a MBP with a 7200 RPM, 320 GB Hitachi Hard drive. I sold the MBP and got a white nvidia MB, but I kept the 7200 RPM drive and used it in the white MB (I did not reinstall the OS). Everything works fine, but I've noticed that it takes a very long time to boot. From the time I turn the MB on, to the time the spinning disk appears, it takes approx. 60 seconds. Other than that, the MB works fine. Should I do a clean install of Leopard. Would this help the slow boot time?
