This post concerns statements made on the Firmware of Maxtor drives. I have run across a few papers lately that the theory for loading the Firmware to the drive have similar explaination to the function of loading firmware to the hard drive. In the two statemets just curious which one would you consider as a more true statement to this fact.

Statement 1:

Maxtor hard drive load firmware to RAM from three sources, 1st the internal boot ROM chip which is located on the PCB, 2nd is the external ROM (Flash ROM) depending on the design of the manufacture design, and 3rd from the Service Area stored on the platters of the hard drive is the most important source.. Modern hard drives are managed by the LBA (Logical Block Addressing) – All read task to write and request the script for the PCB reference to boot the drive are saved in the Service Area. PCB firmware is usually stored in two locations. 1st is the internal ROM chip controller of the PCB, 2nd is the external ROM (parallel or serial Flash ROM) ROM chip located on the PCB. The Internal ROM often can not be repaired and can only be replaced by a new chip. Information stored on the external ROM are always read first and if this chip fails in the process the hard drive can not be booted, or the system will be recognized by its factory alias.

Statement 2:

Service Area of a hard drive contains critical information that the drive needs to function properly in the form of specialized micro code stored in the RAM. The microcode is loaded into the RAM from three sources, 1st the marked ROM inside the processor chip (or otherwise know as the internal boot ROM), 2nd source is the Flash ROM (or otherwise known as the external boot ROM), and 3rd is the drives’ service area if it is installed on the hard drive. This information is often specifically programmed to the board of the drive during the drive's construction to meet each individual drive's specifications, and as a result when the Firmware fails this information must be reconstructed.

Both statements are correct but which one would you consider to be the more true and complete statement here? Just curious.
