Final answer:
Huan should begin by determining the purpose of the technical documentation to guide content, then identify the audience to customize the material. He should use modes and media that effectively reach and inform the audience, and gather necessary data through research to create comprehensive documentation.
Step-by-step explanation:
When Huan is composing technical documentation for a computer hard drive, he should begin gathering information by first determining the project's purpose to guide the content and approach. Next, he should identify the audience to tailor the documentation to their needs and level of technical understanding.
It's crucial to define the situation to focus on the specifics of the hard drive and its applications. The purpose might be anything from instructing users on how to install the hard drive, to providing technical specifications for professionals. A thesis or hypothesis could be on the potential impact of the hard drive on system performance.
When planning his project, Huan should consider the modes and media that will be most effective in reaching his audience, as well as how to support his argument or information. This may involve research, interviews, and other methods of data collection to gather a comprehensive understanding of the topic. He should use a graphic organizer to outline this information, strategize on what he still needs to learn, and develop a plan to collect that data.
