Exactly what the title says, my current PowerBook hard drive works just fine but it's the original 80GB 5200RPM drive from 2005, so it's a little slow. I'm looking for something 7200 RPM and at least 100GB. Not sure where to buy from either, I looked on ebay but couldn't find any legit looking sellers. Also, I have looked at the SSD options but it's way to expensive to sink into a 10 year old laptop. Suggestions?
