I gave my older iBook (466mhz SE DVD, FW) to my brother. He has a 10gb HD. I have noticed the iBook is running painfully slow with 320mb RAM and OS X 10.3. I know it ran fine with 10.2. Anyway the iBook is REALLY sluggish. Takes like 5-10 minutes to startup. Waking from sleep is a pain. And the iBook runs worse than my old G3 MiniTower 333mhz. I noticed the hard drive tends to click a lot. I tried shaking the iBook to see if it was loose but nothing made a sound. I guess I should replace the Hard Drive, maybe with a 20gb or 30gb. I know a good place to get them but, I want to make sure it's the Hard Drive. I also think the DVD drive is starting to go...to bad those are VERY expensive. Any advice? Thanks a lot!
