Embodiment Construction

[0017] In order to further illustrate the embodiments, the present invention provides drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be combined with related descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should understand other possible implementations and advantages of the present invention.

[0018] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Different methods are adopted for the different scratch positions of the hard disk. The scratch positions are divided into outer edge scratches and inner ring scratches. In this embodiment, the repair method for the inner ring scratches is as follows: figure 1 As shown, the Seagate hard disk inner ring scratch data recovery method in this embodiment includes ...

Abstract

The invention relates to a Seagate hard disk inner ring scratch data recovery method. The method comprises the steps that S1, cleaning the surface of a disk in the rotation process of the disk; S2, increasing the diameter of a magnetic head limiting column so as to limit the magnetic head to move to the scratched inner ring of the disc; S3, replacing the magnetic head of the hard disk with a brand-new magnetic head, and completing the assembly of the hard disk; and S4, performing power-on identification on the assembled hard disk, establishing a data recovery task, exporting all data in the hard disk, and finishing data recovery. The Seagate hard disk inner ring scratch data recovery method solves the problem that data recovery cannot be conducted on hard disk scratches in the prior art, and is a major breakthrough in the field of hard disk scratch data recovery.

Description

technical field [0001] The invention relates to the field of hard disk repair, in particular to a method for recovering scratched data on the inner ring of a Seagate hard disk. Background technique [0002] Usually, when the mechanical hard disk is working normally, the head responsible for reading and writing data is suspended on the surface of the disk by the air cushion effect generated by the adjustment and rotation of the disk. When the disk has a bad sector during use, the head will be under the control of the servo system. The reading and writing height between the magnetic head and the disk is adjusted through the deformation of the thermal material. When the hard disk is subjected to external magnetic impact or deformation and damage of the magnetic head, the magnetic head will touch the disk. When the platter of the hard disk is being adjusted and rotated, it is easy to cause scratches on the platter. Since the storage of the disk is continuous, that is, the CHS t...
