    I know that hardware comes with firmware ... but I don't understand what it does?

    Specifically, the hard drive; its firmware.

    Firmware is software instructions that are read by the processor, right? ROM, exactly?

    It is read-only-memory. But what does it do and what is it exactly needed for?

    I thought the hard drive's actuator arm was controlled by the dependency of the kernel under an operating system?

    Or is the firmware to guide the arm when it reads and writes over the platter, writes to certain sectors, etc.?

    I really am interested in this, but nothing seems to explain this; no source.

    I mean do the kernel's base instructions alarm the hard drive's firmware to take action, resulting in the desired operation or instructing?

    How does this make sense? I am curious about this, and would really appreciate it if some one here knew more on this than me.
