Method of detecting and protecting falling portable computer hard disk through software monitoring driver

摘要

In a method of detecting and protecting a hard disk of a falling portable computer, a falling sensor detects a falling state of a portable computer and sends an interrupt signal to a keyboard controller of the computer, and a falling state signal is responded at a default signal port of the keyboard controller. A software monitoring driver executes polling via an I/O driver about the falling state signal at the default signal port of the keyboard controller, and determines based on the falling state signal whether to actuate a hard disk protection mechanism, in which the software monitoring driver interrupts hard disk data access on the computer via a hard disk driver, and causes a system BIOS of the computer to send a parking control signal to the hard disk.
