体の盗難防止策にはならないという欠点がある。Since the above-mentioned conventional method for controlling a hard disk device is a protection control method for files in a hard disk, the portable small hard disk device itself, which has been expanding in the market in recent years, is stolen. It has the drawback of not being a preventive measure.

とを実行することを特徴とする。A method of controlling a hard disk drive according to the present invention comprises a first means for reading a device number unique to an information processing device, a second means for storing the device number, and a second device for storing the device number. The third means for reading the device number from the means for comparing with the device number read by the first means and the command from the information processing apparatus when the comparison result by the third means matches. And a fourth means.

“０”に初期化されているフラグに“１”をセットし、
電源投入時動作を終了する。First, when the power of the hard disk device is turned on, an interrupt 1 occurs in the information processing device, and the information processing device sends out its own device number 2 to the hard disk device. After acquiring the device number, the hard disk device reads the device number stored in the device, for example, stored in the ROM, and compares the two. If they match, set "1" to the flag that has been initialized to "0" in advance,
When the power is turned on, the operation ends.
