A method for repairing no_host and 3005_error failures of Seagate hard disk at the same time

Abstract

The invention discloses a method for recovering concurrent NO-HOST and 3005-ERROR faults of a Seagate hard disk. The method is characterized by comprising the following steps of: S1, obtaining an HDD setting module and rewriting a header file of the HDD setting module; S2, searching a first identifier in the HDD setting module, and obtaining a second identifier and a first characteristic value; S3, searching the second identifier and writing the first characteristic value into 4 bytes after the searched second identifier; S4, taking a first address of the first identifier in the HDD setting module as a start position to shift backwards for 0x10 bytes, taking the shifted address as a start address, taking the previous byte address of an end identifier as an end address, moving data in a range from the start address to the end address forwards for 8 bytes, and writing a second characteristic value into 8 bytes before the end identifier; S5, searching a third identifier in the HDD setting module, and setting 4 bytes after the third identifier to be zero; and S6, writing the rewritten HDD setting module back to a faulty hard disk, and verifying that the faults are recovered.

Description

technical field [0001] The invention belongs to the field of data restoration, and relates to a method for repairing a hard disk, in particular to a method for repairing a Seagate hard disk where NO_HOST and 3005_ERROR failures occur simultaneously. Background technique [0002] As an important member of storage devices, hard drives play an extremely important role. Most of our data is stored through hard disks. This phenomenon of large-scale use of hard disks to record data is even dubbed "civilization based on magnetic media". Therefore, the sharp increase in data storage and the importance of data , making data recovery even more important. [0003] Founded in 1979, Seagate is currently the world's largest manufacturer of hard drives, magnetic disks and read-write heads, headquartered in Scott Valley, California, USA. Seagate is a global leader in the design, manufacture and sales of hard drives, providing products for enterprises, desktop computers, mobile devices and ...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art and the above-mentioned problems, the present invention proposes a method for repairing both NO_HOST and 3005_ERROR faults in the Seagate hard disk, by modifying the HDD setting module and writing back the modified HDD setting module to the faulty hard disk, thereby repairing the fault failure and make the failure hard disk can be identified, solve the technical problem that the failure cannot be repaired by the instruction repair mode in the prior art, and the method includes the following steps:
