Greetings: I've followed the groups advice over time and now I have a problem to ask about. An "expert" (not from this Cube List) suggested that I could install a new Hard drive by just installing it and booting it up, using my latest OS CD. I've had No luck doing so. After trying it with a new 120Gg. HD, I brought the Drive down to my local Apple dealer and asked them to format it with Mac extended format. They tried and said it was a bad drive. I exchanged it for another... still won't boot from my OS CD. What now? I'm starting to get more money tied-up in mail, insurance, and the local dealer- then I spent on the new Hard Drive. Please, any suggestions. Jim Dawson G4 Cube 500DP 1.5Gg Ram
