Abstract:
1. An information processing apparatus, comprising: a hard disk drive which is capable of retracting a head to a data-free landing zone; an acceleration sensor which detects acceleration; a determination section which obtains high frequency components from acceleration information detected by the acceleration sensor, obtains a vibration level corresponding to the obtained high frequency components, compares the vibration level with a threshold value which is set up, and determines whether or not there is a necessity to retract the head of the hard disk drive to the data-free landing zone; a threshold value setup section which allows a user to change the threshold value and set up the changed threshold value; and a display section which is capable of displaying information for the user, wherein the threshold value setup section obtains information about the set up threshold value that the user has input on a man-machine interface screen on the display section, periodically obtains a vibration level obtained at the determination section, and displays the obtained threshold value and the obtained vibration level simultaneously on the man-machine interface screen such that the user can compare the threshold value with the vibration level.
