Embodiment Construction

[0023] 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.

[0024] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Different methods are used for different scratch locations on hard disks. The scratch locations are divided into outer edge scratches and inner edge scratches. In this embodiment, it is a repair method for outer edge scratches. This method has the following restrictions: , that is, only one side of the two sides of the disc is allowed to be scratched, that is...

Abstract

The invention relates to a method for recovering scratched data on the outer edge of a Seagate hard disk. The method includes: S1: cleaning the disk; S2: replacing the magnetic head; S3: cutting off the magnetic head corresponding to the scratched side of the disk; S4: closing the scratch Activate the magnetic head corresponding to the damaged side; S5: After installing the disk and the cut magnetic head, power on to confirm whether it can be recognized, if yes, enter S6; otherwise, replace the new matching magnetic head, return to S3; S6: Back up the firmware; S7: mirror the data of the magnetic head corresponding to the unscratched side; S8: stop the motor, and separate the circuit board from the hard disk when the circuit board is powered on; S9: replace the brand new magnetic head, And install and position the magnetic head stopper; S10: reassemble the hard disk body and the circuit board; S11: mirror the data on the scratched side. The invention proposes a data recovery method aiming at the scratches on the outer edge of the Seagate hard disk, which solves the problem in the prior art that the data cannot be recovered from the scratches on the hard disk.

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 outer edge 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...
