Abstract

The invention provides a hard disk protection method, which is that: a three-dimensional acceleration induction chip is positioned as a vibration sensor in a computer system, so as to detect the motion state of the hard disk; when the hard disk exceeds the vibration with set vibration intensity, ultra-intense vibration alarm is sent out immediately and the system immediately stops data read-write operation of magnetic heads in the hard disk on the hardware disk surface temporarily; after the vibration disappears, the system restores the data read-write operation of magnetic heads in the hard disk on the hard disk surface at once, thereby reducing the damage of the hard disk surface due to vibration under read-write state, realizing the purpose of protecting the hard disk, not only prolonging the service life of the hard disk, but also effectively protecting the precious data in the hard disk from being lost due to hard disk damage.

Description

A kind of hard disk protecting method

1, technical field

The present invention relates to a kind of computer hard disk protecting method, particularly relate to a kind of hard disk protecting method of the specific use notebook computer that can under rugged surroundings, normally use.

2, background technology

Along with development of science and technology, notebook computer is popularized gradually.For public security, the People's Armed Police, special users such as army, in being in the rugged surroundings of strenuous vibration, use notebook computer to happen occasionally, hard disk drive generation strenuous vibration when hard disk carries out read-write operation, this situation is easy to cause the magnetic head mechanical arm to damage or the magnetic head of working is beaten and causes loss of data on disc, even causes hard disk bad track to occur, causes hard disk corruptions.

Effectively reduce influence and damage that the notebook computer hard disk is not brought by the main frame vibrations, not only can reduce user's maintenance cost, and for most of users, the value of institute's data on file will be far longer than the value of hard disk itself in the hard disk.

Therefore, in order to reduce hard disk corruptions, better protection hard disk at work improves the safe reliability of hard disk, and we research and develop and have designed a kind of hard disk protecting method.

3, summary of the invention:

Technical problem underlying to be solved by this invention provides a kind of hard disk protecting method; detect by the motion state of sensor hard disk; when hard disk generation strenuous vibration; suspend the operation that hard disc magnetic head reads and writes data on the hard disk card; thereby the hard disk under the minimizing read-write state reaches the purpose of protection hard disk because of the infringement that vibrations cause.

For achieving the above object, the invention provides a kind of hard disk protecting method, this method is the three-dimensional acceleration induction chip to be set as vibration transducer in computer system, motion state to hard disk detects, when hard disk is subjected to exceeding the vibrations of setting oscillation intensity, send superpower vibration alarming signal immediately, system suspends the data read-write operation that hard disc magnetic head carries out immediately on the hard disk card, after vibration disappearance, the data read-write operation that the system recovery hard disc magnetic head carries out on the hard disk card, damage because of vibrating the card that hard disk is caused under read-write state thereby reduce hard disk, reach the purpose of protection hard disk; The protection step is as follows:

1) by be arranged in the computer cabinet or the hard disk circuit in the three-dimensional acceleration induction chip in real time for the worker of system vibration detection signal, whether the vibration induction signal intensity that system's real-time judge is obtained surpasses preset critical, if surpass, then start the hard disk protection program, all processes of carrying out hard disk read-write operations are cut off hang-up temporarily, and the read-write operation of fixed disk file stops; If be no more than, then hard disk continues operate as normal;

2) after vibration disappearance, be arranged in the computer cabinet or the hard disk circuit in the three-dimensional acceleration induction chip provide the induced signal of oscillation intensity within preset critical by detecting to system, the work of system start-up hard disk recovers the read-write operation of disk.

The good effect that hard disk protecting method of the present invention had is by the lasting detection to the hard disk motor message; when hard disk generation strenuous vibration; can suspend the read-write operation of hard disc magnetic head immediately; thereby can effectively reduce the damage that magnetic head causes disc; thereby protected hard disk; promptly prolong the serviceable life of hard disk, can also effectively protect the valuable data in the hard disk not lose because of hard disk corruptions.

5, embodiment

Describe hard disk protecting method of the present invention in detail below in conjunction with process flow diagram and do following detailed description.

By three dimension acceleration sensor the motion state of hard disk is continued to detect and obtain vibration signal, judge whether the induced signal intensity of being obtained has surpassed preset value, specifically comprise: a sensor is set, obtain the work state information of current hard disk by the output of obtaining sensor in real time, further judge that then the current disk state information of obtaining is whether within the span that sets in advance, if within scope, this status information is not done any processing; If not within preset range, then send a marker and start hard disk protection, when disk state information returns within the preset value, end hard disk protection otherwise send marker once more.

Described startup hard disk protecting method; all processes of carrying out hard disk read-write operations are hung up temporarily; suspend the fixed disk file read-write operation; specifically comprise; all read or write operations to hard disk carry out real time monitoring; enumerate that all carry out the process of read-write operation in the system to file; when obtaining the marker that sensor sends over; all read-write processes of enumerating of temporary suspension; end the read-write operation of magnetic head; when obtaining the vibration disappearance marker once more, recover all read-write processes, hard disk continues operate as normal.

Detect by the motion state of induction chip from such scheme a kind of hard disk protecting method of the present invention as can be seen hard disk; when the hard disk strenuous vibration; start hard disk protecting method; reduce the infringement that read-write operation causes hard disk effectively; thereby reduced the possibility that hard disk is damaged, protected hard disk.

Claims

1. the invention provides a kind of hard disk protecting method, it is characterized in that in computer system, being provided with the three-dimensional acceleration induction chip as vibration transducer, motion state to hard disk detects, when hard disk is subjected to exceeding the vibrations of setting oscillation intensity, send superpower vibration alarming signal immediately, system suspends the data read-write operation that hard disc magnetic head carries out immediately on the hard disk card, after vibration disappearance, system recovers the data read-write operation that hard disc magnetic head carries out immediately on the hard disk card, damage because of vibrating the card that hard disk is caused under read-write state thereby reduce hard disk, reach the purpose of protection hard disk; The protection step is as follows:
