Hard disk control method and device

Abstract

A hard disk control method comprises setting a data recording path to be one hard disk of at least two hard disks; controlling other hard disks which are not set to be the data recording path in the at least two hard disks to enter into a deep dormant state; cyclically executing the following steps which comprise, executing a countdown command, controlling one hard disk which is in the deep dormant state to enter into an awakening state when the countdown is ended, setting the data recording path to be the hard disk which enters into the awakening state and recording the data to be in the hard disk which is in the awakening state from a next wiring-in command, judging whether no data is wrote into the hard disk which is in front of the hard disk which is set to be the data recording path and enters into the awaking state or not, and controlling the front hard disk to enter into the deep dormant state if yes. The invention also provides a hard disk controlling device. The hard disk controlling method and device controls alternative operation of the plurality of hard disks and prolonging the service life of the hard disks.

Description

technical field [0001] The invention relates to the field of computer control, in particular to a hard disk control method and device. Background technique [0002] As a common storage device, hard disks are mainly divided into ordinary hard disks and wide temperature hard disks. The normal working time of ordinary hard disk is to work continuously for 5 days, 8 hours a day; wide temperature hard disk, on the basis of ordinary hard disk, has made special treatment for its internal mechanical structure, chemical materials and electronic devices, so it can work in wider temperature range. As far as the design characteristics of the hard disk are concerned, it has a very precise mechanical structure design inside, and is equipped with a control chip and control software to record data on the high-speed rotating disk. [0003] After a large amount of data statistics, when the working time of ordinary hard disks exceeds the specification of 5×8, certain uncertain faults will ra...

AI Technical Summary

Problems solved by technology

[0003] After a large amount of data statistics, when the working time of ordinary hard disks exceeds the specification of 5×8, some uncertain failures will occur randomly, such as data reading and writing errors, abnormal state of the hard disk controller, etc., resulting in unstable and unreliable data transmission

Therefore, when it is necessary to use an ordinary hard disk as a video surveillance data recording storage device (such as applying an ordinary hard disk to a bayonet industrial computer in the intelligent transportation industry), it often needs to work continuously for 24 hours until regular maintenance and repair. It will definitely exceed its specifications, reduce the life of the hard disk, and even cause application failure
