A method of repairing head failure of Seagate hard disk

Abstract

The invention discloses a method for repairing faults of the magnetic read of a Seagate hard disk. The method includes the following steps that: S1, selecting hard disks from normal hard disks as matching disks, wherein the model number, the first three numbers of the series number and firmware version number of each selected hard disk are consistent with those of a fault disk: S2, searching magnetic read deviation rates of the matching disks and the fault disk, searching a matching disk of which the magnetic read deviation rate is most approximate to that of the fault disk; and S3, recombining and replacing magnetic read parameters in the fault disk (ROM). With the method of the invention adopted, the problem of incapability of realizing adaptation after the magnetic read of a hard disk is replaced can be solved; through two times of screening, the matching disk which is most approximate to the fault disk can be found fast and accurately, and data incompatibility of the matching disk in an adaptation process can be prevented; and SAP data can be found and re-combined, and the success rate of hard disk repair is high, and repair time can be reduced.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for repairing a head failure of a Seagate hard disk. Background technique [0002] The hard disk stores data through the reading and writing of the magnetic head. Due to the long-term use of the hard disk and the influence of unspecific factors, such as shaking the hard disk during the working process of the hard disk, the magnetic head of the hard disk will be damaged, resulting in the ATA status of the hard disk being always busy or necrotic. At this time, the hard disk has no way to read the data in the hard disk, and there will be phenomena such as inability to seek, knock on the disk, abnormal noise, or even failure to start. [0003] At present, the main way to repair the head failure of Seagate hard disk is to replace the magnetic head, but after the replacement of the magnetic head, it is easy to cause the mismatch between the magnetic head and the d...

[0002] The hard disk stores data through the reading and writing of the magnetic head. Due to the long-term use of the hard disk and the influence of unspecific factors, such as shaking the hard disk during the working process of the hard disk, the magnetic head of the hard disk will be damaged, resulting in the ATA status of the hard disk being always busy or necrotic. At this time, the hard disk cannot read the data in the hard disk, and there will be phenomena such as inability to seek, knock on the disk, abnormal noise, or even failure to start up.

[0003] At present, the method of repairing the failure of the head of the Seagate hard disk is mainly to replace the head, but after the replacement of the head, it is easy to cause the mismatch between the head and the disk body, and the hard disk cannot work normally at this time.
