Hard disk data protecting method and computer storing system

Abstract

The invention provides a hard disk data protecting method. The method includes the following steps of judging whether the last operation of a hard disk is the last datum of a register table or not through a preset data register when monitoring that a working power supply is powered off, if yes, operating data of the whole register table to the hard disk, if not, importing the data, backed up in the data register in advance, of the whole register table to the hard disk, operating the data of the register table to the hard disk, judging whether the last command cached in the data register is complete or not, and determining whether to operate the cached hiccup data of the data register to the hard disk or not. Through the operation, the data integrity of the hard disk can be protected, and meanwhile security of the system is improved. The invention further provides a computer storing system. By means of the system, when the working power supply is powered off suddenly, the stability of the system can be effectively ensured by judging the operation of the hard disk at the moment and providing the corresponding operation data.

Description

technical field [0001] The invention relates to the computer field, in particular to a hard disk data protection method and a computer storage system under instantaneous power failure. Background technique [0002] The large-capacity storage devices used by existing computers are generally mechanical hard disks or solid-state hard disks. Mechanical hard drives use mechanical fan blades to store data, and use mechanical heads to read or write data; solid state drives use flash memory as a storage medium, and use electronic addressing to read and write data. During the use of the computer, it is likely to encounter a sudden power failure or forced shutdown of the system, which will cause the hard disk to suddenly lose power. Mechanical hard disks have many protective measures for the hard disk data and the mechanical device of the hard disk itself, but in the event of a sudden power failure, the current hard disk only has the mechanical protection measures of head reset, whic...
