Hard disk is one of the main storage media of computer, composed by one or several glass/aluminum-made platters. The majority of hard disks are fixed hard disk permanently fixed on hard disk drive; so many users are unfamiliar with hard disk structure. Ordinary hard disk are constituted by control circuit and HDA among which control circuit includes interface, DSP, processor, Rom, cache, hear driver circuit and platter driver circuit and HDA contains hard disk cavity, spindle motor, hard disk head, magnetic head and voice coil motor, etc. Currently, hard disk has become an indispensable tool for storing data and files, which naturally means that hard disk users are very likely to suffer great loss on data loss occurs. After encountering data loss, employing data recovery software to perform hard disk recovery is the first idea coming into user's mind.

Startup process of hard disk
Hard disk is like a computer, which needs a process from powering up to getting ready. Now I am to share with user the hard disk startup process:
1. After being powered on, microprocessor first runs programs in ROM and parts of hard disks check component integrity.
2. Spindle motor starts; head begins operation when revolving speed reaches certain grade, locating to platter firmware zone and reading hard disk firmware and bad track table. At this moment, some hard disks will compare serial number on ROM memory with that on platter. If they are inconsistent, hard disk will stop startup process.
3. After all requisite firmware is normally read, disk will be ready, wait for command and process data read/write operations.
