Automatically switching-off system of hard disk for computer failure

Abstract

The invention provides an automatically switching-off system of a hard disk for a computer failure. In the system, a GPIO pin is defined in a south bridge or Super IO or FPGA, and the major function of the pin is to control a power supply switch of the hard disk; when the system detects an error or a failure existing in the data read-write of the hard disk, the switching of a power supply is realized by the GPIO so as to achieve the purposes of energy saving and data safety; when the system detects that a certain hard disk in the system generates a failure in a software mode, a host computer can send out a control signal 1 for switching off the power supply of the hard disk and inform a control module of the hard disk of stopping the communication with the failure hard disk; after the control module of the hard disk finishes the backing-up of data before and after the failure, a control signal 2 can be sent out; only when the control module of the power supply receives the two control information of the control signal 1 and the control signal 2, the control module of the power supply sends out the control signal for switching off the power supply of the failure hard disk; and after the power supply of the failure hard disk is switched off, the purpose of electricity saving is realized and the safety of the data is ensured.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a system related to data security protection of computer hard disks, power failure and energy saving of faulty hard disks, and the like. technical background [0002] With the continuous development of computer technology, people have higher and higher requirements for storage, but the security of data in the hard disk has also attracted much attention. There may be certain errors in fetching, but at this time the hard disk may continue to work and continue to use system power, which is also an important issue for energy saving. When the data on the hard disk is unreliable, turn off the hard disk to reduce power Therefore, a system that automatically cuts off power by detecting hard disk failures is required to achieve data security and energy saving. Generally, when data read / write errors or bad sectors occur in hard disks, the faulty hard disk continues to consume the pow...

AI Technical Summary

Problems solved by technology

Generally, when data read / write errors or bad sectors occur on a hard disk, the faulty hard disk continues to consume the power of the system because the system administrator did not find out the fault or replace the hard disk in time, which is a waste of energy for the entire system.

When wrong data is read, it will lead to data security problems of the system,
