Abstract: PROBLEM TO BE SOLVED: To provide the effective and highly practical protection mechanism of a magnetic disk device, capable of finely dealing with the used situation of a portable terminal device.
SOLUTION: This protection mechanism is provided with a registered stable position data storing part 53 for storing the information of a stable state indicating the setting of a magnetic disk device in a stable using environment, a stationary state measuring part 51 for determining whether the magnetic disk device is in a stationary state or not based on the information of acceleration applied to the magnetic disk device and detected by a sensor 20, and an operation state determination part 54 for determining whether the stationary state is the stable state stored in the registered stable position data storing part 53 or not when the magnetic disk device is determined to be in the stationary state, and setting a prediction detecting sensitivity for predicting the occurrence of shocks on the magnetic disk device based on the result of the determination. A magnetic head operation control part 60 retreats a magnetic head 11 when the prediction of shock occurrence is detected based on the detecting sensitivity.

Abstract: PROBLEM TO BE SOLVED: To perform hot-undocking of an expanding device, for instance, without making a portable PC body shutdown. SOLUTION: In the case an eject event is detected when the portable PC body 11 having a main battery 21 is subjected to hot-undocking from an expanding device 41 having a sub battery 42, the state of the battery 42 is judged. As a result, when the battery 42 is in the middle of discharge, a power supply route to the portable PC body 11 is switched from the sub battery to the main battery. When the battery 42 is in the middle of being charged, the charging is stopped. Then, hot-undock processing is carried out.

Abstract: PROBLEM TO BE SOLVED: To provide an information processor which prevents the protection function of a disk drive for the anticipated impacts from causing troubles in the predetermined processing, and also to provide a control method of the information processor, and a program and a recording medium thereof.
SOLUTION: When the predetermined conditions are fulfilled after the magnetic disk drive 13 is made highly shockproof, a second prediction means 20 issues a second prediction that the anticipated impact is not imminent. When power switching is made impossible by the protection function of the magnetic disk drive 13, a condition relaxation means 28 relaxes the conditions for issuing the second prediction in the second prediction means, and prompts the disk drive 13 to return to the state allowing to read/write the data. The information processor 10 has a protection function to switch the drive 13 to the highly shockproof state unable to read/write the data when an impact to the magnetic disk drive 13 is anticipated, and a power switching function to properly switch the drive 13 to the power saving mode. In the power switching function, disk accessing is requested, and the power switching is often suspended for a long time if an impact is predicted to be imminent to the disk drive 13. Such cases are prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a protective mechanism for a magnetic disk which enhances the resistance of the magnetic disk to impacts by retreating a magnetic head according to the state of a magnetic disk unit and which meticulously sets the conditions for retreat of the magnetic head, and is effective and highly practicable. SOLUTION: The protective mechanism is provided with a sensor 20 and sensor driver 31 which acquire information relating to a change in the environment for the magnetic disk unit 10, a shock manager 32 which analyzes the information acquired by the sensor driver 31 together with the history thereof and carries out impact prediction by judging the state in which the magnetic disk unit 10 is placed and an HDD filter driver 33 which controls the operation of the magnetic disk unit 10 including the retreat of the magnetic head on the basis of the result of the prediction by the shock manager. Further, the mechanism can also be provided with a diagnostic processing section for investigating whether the retreat of the magnetic head can be completed or not prior to the occurrence of the impact and for diagnosing whether there is a possibility of the occurrence of trouble in the magnetic disk or not.
