HARD DISK DEVICE OF IDE TYPE AND CONTROLLING METHOD THEREOF

摘要

PURPOSE: A hard disk device of an IDE(Integrated Device Electronics) type and a controlling method thereof are provided to connect plural storing instruments to one port of a controller circuit. CONSTITUTION: One port of a controller circuit and plural storing instruments are connected by an IDE bridge. In a booted state of a system, hardware information for each storing instrument is requested through the IDE bridge. The IDE bridge combines the hardware information for generating virtual storing instrument information. Then, the virtual storing instrument information is transferred to the controller circuit. A virtual target address is read for sampling an address for a real storing instrument corresponding to the virtual target address. A command is transferred to the sampled address. Data is transferred between the controller circuit and the address of the real storing instrument through a separate data transfer loop.
