DEVICE AND METHOD FOR INSERTING/EJECTING IDE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for inserting/ejecting integrated device electronics(IDE) devices with which system failure does not occurs in the main body of a computer by a dummy circuit when performing hot-line insertion/ejection. SOLUTION: At the time of hot-docking a docking IDE device 14, a dummy IDE device 22 performs initial setting in place of an IDE controller so as to operate the docking IDE device 14 and in the case of hot-undocking, issues a head saving command or the like so as to prevent data destruction in the docking IDE device 14 and executes an operation such as making the impedance of an IDE bus for docking and a power source 20 for docking high. The IDE device (DVD, CD-ROM drive or HDD) not supporting hot-docking/hot-undocking can also be hot-docked/hot-undocked as well.
