Description

Technical Field

[0001] The present invention relates to the technical field of mechanical hard disk diagnostic equipment, and more specifically to a mechanical hard disk flaw detection mirror device. Background Art

[0002] A mechanical hard disk flaw detection mirror device is a device used to detect and diagnose internal faults and damages of mechanical hard disks. It is usually used in the data recovery industry or data security field. It is a key tool to ensure the security and reliability of hard disk data.

[0003] Mechanical hard disks are particularly sensitive to changes in the external environment due to their sophisticated internal mechanical structures. In extreme situations such as fire, the high temperatures to which the hard disk is subjected can easily cause physical deformation of the disk and damage to the head and platter. The vibration and impact caused by the explosion may cause the head to contact or scratch the platter, resulting in bad tracks and scratches. Flooding may cause the internal structure of the hard disk to rust, further exacerbating physical damage. Even after physical repair, these hard disks still face problems with bad tracks and scratches during data recovery. These problems greatly increase the difficulty of data recovery and significantly reduce the successful recovery rate of key monitoring data. The problem needs to be solved by setting a bad track mirroring strategy.

[0004] However, the bad sector jumping mechanism of traditional bad sector mirroring is based on sectors and is not suitable for mechanical hard disks with physical damage. Traditional bad sector jumping can only target logical bad sectors. When mirroring a hard disk with physical damage, it is still possible to read the damaged area after jumping a fixed sector size. Therefore, traditional bad sector mirroring cannot determine the damage type of the mechanical hard disk, which can easily cause secondary damage to the mechanical hard disk and expand the fault.

[0005] Therefore, how to provide a flaw detection mirror device that can accurately determine the damage type of a mechanical hard disk and improve data recovery rate and recovery integrity is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] In view of this, the present invention provides a mechanical hard disk flaw detection mirror device, aiming to solve the above technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A mechanical hard disk flaw detection mirror device, comprising:

[0009] A housing, wherein an inner cavity of the housing is detachably connected to a circuit board, and an MCU controller is integrated on the circuit board;

[0010] A storage unit, the storage unit is located outside the housing and is electrically connected to the MCU controller;

[0011] A diagnostic module, which receives signals and instructions from the MCU controller, scans and diagnoses fault data, and determines the damage type;

[0012] A mirroring module receives signals and instructions from the MCU controller, performs mirroring and recovery according to the damage type determined by the diagnosis module, and stores the images in the storage unit.

[0013] Through the above technical scheme, the present invention discloses a mechanical hard disk flaw detection mirror device, which uses an MCU controller as a control unit and cooperates with a diagnostic module to scan and diagnose the data in the damaged hard disk, realize data reading, register status monitoring, current fluctuation monitoring and SMART monitoring of the damaged hard disk, and accurately distinguish the hard disk damage type; the mirror module realizes complete data backup and recovery and preservation, and maximizes the recovery of data in the hard disk damaged by extreme conditions such as fire. According to the monitored register status and current fluctuation of the damaged hard disk, the mirror strategy is adjusted in real time. The number of jumped sectors is dynamically changed, which is basically proportional to the head width and slightly larger than the width of a continuous physical bad sector. The diagnostic module and the mirror module are software modules. Through the cooperation scheme of the software module and the MCU controller, it can support more types of hard disk models with higher scalability, and can automatically adjust the number of jumped sectors according to different models of hard disks to realize a more optimized mirror strategy, directly interact with the hard disk through the circuit, avoid multiple reading and writing, and can monitor the hard disk status in real time, greatly reduce the secondary failure rate of the hard disk, and improve the efficiency and reliability of data recovery.

The diagnostic module and the mirror module are software modules, which are pre-installed in the display screen. The ATA standard instruction set is sent through the software module, transmitted to the MCU controller, parsed by the MCU controller and sent to the hard disk through the circuit.

This process is to transfer the data safely to a reliable storage medium before conducting in-depth data recovery and analysis, so as to avoid further damage to the original damaged hard disk during the processing process; the mirror module copies the data to the second hard disk through the communication transmission interface according to the analysis results of the diagnostic module, so as to realize data mirroring and recovery. In this process, the MCU control monitors the hard disk status in real time, and dynamically adjusts the mirroring strategy to adapt to the physical damage of the hard disk.
