Abstract

The invention provides a device for monitoring and repairing a damaged sector of a hard disc. The device comprises a damaged sector managing unit, a disc driving unit, a damaged sector monitoring unit, a universal cache memory unit and a damaged sector replacing unit, wherein a database memory partition for loading a damaged sector database is divided in the hard disc by the damaged sector managing unit when a system is started, a mapping sector is divided from the database memory partition when the judgment of the damaged sector monitoring unit shows that the damaged sector exists in the current sector and writing-in operation is carried out by the universal cache memory unit, and the indexing information of the bad sector and the mapping sector is stored by the damaged sector database; a system file data block in which the sector corresponding to the damaged sector is positioned is marked as a damaged block by the damaged sector replacing unit during reading operation, and the information of the bad sector is duplicated to the mapping sector by the damaged sector replacing unit; when writing-in operation is successfully carried out on the mapping sector by the disc driving unit, the corresponding sector of the damaged sector database is updated by the damaged sector managing unit. The invention further provides a corresponding method. Through the utilization of the device and the method, the technical problem in the prior art that the damaged sector cannot be automatically monitored or the damaged sector cannot be automatically replaced is solved.

Description

[0001] technical field [0002] The invention relates to the technical field of computer storage media, in particular to a hard disk bad track monitoring and repairing device and method. Background technique [0003] Hard disk bad sectors can be said to be a fatal failure of the hard disk. After the hard disk has bad sectors, the hard disk often means the end of the hard disk life. After the hard disk has bad sectors, not only some bad sectors are unusable, but also directly affect other available sectors. disk sector, causing the entire hard disk to be damaged. When the hard disk has bad sectors, it means that the stored data will be unsafe. Therefore, timely discovery of bad sectors can minimize losses. [0004] Currently, hard disk monitoring technologies mainly include: AUTOFSCK, Self-Monitoring Analysis and Reporting Technology (Self-Monitoring Analysis and Reporting Technology, S.M.A.R.T) and Disk Array (Redundant Arrays of Inexpensive Disks, RAID). However, the a...
