Hello, This thing is talking about notebooks and notebook upgrades. But yet it talks about unscrewing a bottom pannel and disconnecting cables. The notebooks I've had the pleasure of working with do not have any cables and use SATA drives. Also, the majority of notebook drives are 5400 or 7200 RPM drives. Am I missing something?
