Problems solved by technology

However, the cost of RAID is high, and more than two hard disks are required to form a disk array. For blade boards under the ATCA (Advanced Telecom Computing Architecture) architecture, replacing all boards with hard disks with disk arrays will undoubtedly increase product costs.

Embodiment Construction

[0056] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0057] Such as figure 1 As shown, in the hard disk bad track monitoring method based on embedded Linux of the present invention, the hard disk is divided into three partitions: a data storage partition, a backup partition, and an original data set partition.

[0058] The data storage partition is a normal hard disk partition. The backup partition serves as a backup and does not store any files. Unless a bad sector is found in the data storage partition, no read or write operations will be performed on the partition. In order to save the data more efficiently without compressing the data during subsequent dumping, the data storage partition is the same size as the backup partition during partitioning.

Abstract

The invention relates to the technical field of computer storage medium, and discloses a method for monitoring an embedded Linux-based hard disc bad track. A hard disc is divided into a data storage partition, a backup partition and an original data set area; and an original data set in the original data set area is loaded to a memory when a computer is started. The method comprises the following steps: acquiring healthy state data in the hard disc operation process; carrying out data verification on the acquired healthy state data and standard data in the original data set, so as to judge whether the hard disc has a bad track or not; if a bad track occurs, mounting the backup partition, backing up the data in the data storage partition into the backup partition, generating a mirror image document and transmitting a bad track information report. The invention further discloses an embedded Linux-based hard disc bad track monitoring system. By utilizing the method and the system, monitoring, early-warming and repairing of the hard disc bad track under a non-RAID (Redundant Array of Independent Disc) mode are realized; and meanwhile the cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of computer storage media, in particular to a hard disk bad track monitoring method and system based on embedded Linux. Background technique [0002] Hard disk bad sectors can be said to be a fatal failure of the hard disk. After the hard disk bad sectors appear, the hard disk often means the end of the hard disk's life. After the hard disk appears bad sectors, not only some bad sectors are unavailable, but also others are directly affected. Disk sectors, causing damage to the entire hard disk. When the hard disk has bad sectors, it means that the stored data will be unsafe. Therefore, timely detection of bad sectors can minimize the loss. [0003] There are many reasons for bad sectors on hard disks, such as dust, vibration, static electricity, high temperature, etc. However, the more common reasons in actual use are mainly the following two aspects: illegal shutdown (that is, abnormal power failure); too littl...
