Abstract

See full text

A system, related hard disk drive (HDD) and method are disclosed in which a firmware download to the HDD is accomplished by receiving it from the host and storing it to a first region of a disk in the HDD. The value of a download flag is set once the firmware download is complete. After the system performs an OFF/ON power cycle, it checks the value of the download flag and changes a Logical Block Address mapping a second region of a non-user data region of the disk storing a DOS boot program. The firmware download is transferred from the first region to a third region of the disk or a non-volatile memory device following execution of a boot procedure by the host using the DOS boot program.
