Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of solid-state drives, and specifically to a method for recovering data from a solid-state drive. Background Art
[0002] With the rapid development of information technology, solid-state drives have been widely used in the computer storage field due to their high-speed read and write performance and stability. However, various faults may occur during the use of solid-state drives, resulting in data loss. Currently, common reasons for data loss include physical faults (such as interface damage, circuit damage, abnormal heating, etc.) and firmware faults (such as bad blocks, read errors, module loss, logical bad sectors, and checksum errors, etc.). Traditional data recovery methods often have limitations. For example, they may only be effective for specific types of faults, or the recovery process is complex and inefficient. At the same time, there is also a lack of a clear method for handling cache files, which is likely to waste time and resources during the recovery process. Therefore, a comprehensive and efficient method for recovering data from a solid-state drive is needed to meet the recovery needs of users in case of data loss. Summary of the Invention
[0003] (1) Technical Problems to be Solved
[0004] In view of the deficiencies of the prior art, the present invention provides a method for recovering data from a solid-state drive.
[0005] (2) Technical Solutions
[0006] To achieve the above object, the present invention provides the following technical solution: A method for recovering data from a solid-state drive, comprising the following steps:
[0007] Step 1: Monitoring and cache identification. Monitor the status of the computer file system, use a file monitoring tool (such as FileSystem Monitor) to record the storage space data and the number of files of the solid-state drive partition when the system boots and shuts down, and use a file extension identification tool (such as Extension Analyzer) to identify whether the files with a change in the number of files are cache type files according to the file suffix; for cache files, clarify the processing method that their loss due to power-off can be not recovered.
[0008] Step 2: Trigger hardware scanning. When it is recognized that the number of files decreases and it is not a cache type file, use a hardware scanning tool (such as HD Tune Pro) to perform hardware scanning, not limited to the condition of file deletion by personnel operation.
[0009] Step 3: Establish a secure partition and file copying. Establish a secure partition. The secure partition can be established on another hard disk (such as a mechanical hard disk) or a USB flash drive, or cloud data storage can be selected in the case of an Internet connection (such as using cloud storage services like Baidu Netdisk), and then copy the undamaged files to the secure partition.
[0010] Step 4: Hardware scanning and fault location. Use a professional hardware scanning tool (such as Victoria) to scan the solid-state drive for hardware to identify the type and location of the fault.
[0011] Step 5: Fault repair strategy selection. According to the identification result, adopt the corresponding repair strategy to repair the faulty area.
[0012] Step 6: Fault type differentiation and repair method determination. Identify whether the solid-state drive has a physical fault or a firmware fault. Physical faults include interface damage, circuit damage, and abnormal heating. The reasons for data loss include circuit board deformation, circuit breakage, and abnormal high temperature of the chipset. The corresponding file repair methods are firmware repair (professional firmware repair tools can be used, such as Flash Utility), chip data recombination (chip data recovery software can be used, such as Chip Data Recovery), interface conversion (adopt an appropriate interface conversion device), physical replacement (replace damaged hardware components); firmware faults include bad blocks, read errors, module loss, logical bad sectors, and checksum errors. The corresponding file repair method is to use professional data recovery software (such as R-Studio) for recovery.
[0013] Step 7: Deep scanning and data recovery. Use professional data recovery software (such as GetDataBack Pro) to deeply scan the solid-state drive to recover the lost data.
[0014] Step 8: Data verification and repair. Verify and repair the recovered data to ensure the integrity and accuracy of the data. A data verification tool (such as Data Validation Toolkit) can be used for verification and repair.
[0015] Step 9: Formatting and partition table reconstruction. Reformat the solid-state drive and use a partition management tool (such as Partition Wizard) to reconstruct the partition table.
[0016] Step 10: Data copying and storage. Copy the repaired data to a secure storage medium (such as a portable hard drive, optical disc, etc.).
[0017] Furthermore, in Step 4, the professional hardware scanning tool can be a suitable hardware detection software, such as Victoria, etc.
[0018] Further, in step 1, a dedicated file recognition tool or method is used to recognize cache type files, such as using tools like Extension Analyzer.
[0019] Further, in step 3, the security partition can be established on other hard disks (such as mechanical hard disks) or USB flash drives, or cloud data storage (such as Baidu Netdisk, etc.) can be selected when connected to the network.
[0020] Further, in steps 6 to 8, data is restored by using appropriate data recovery software (such as R-Studio, GetDataBackPro, etc.). The faulty hard disk is connected to the computer, and the software is used to scan and identify the partitions on the hard disk, and the data to be restored is selected for restoration.
[0021] Further, in step 6, the types of physical faults and corresponding repair methods are clarified, such as using FlashUtility for firmware repair, Chip Data Recovery for chip data reorganization, etc.
[0022] Further, in step 6, the types of firmware faults and corresponding repair methods are clarified, such as using professional data recovery software like R-Studio for recovery.

[0031] Figure 1 It is a schematic diagram of the method flow of the present invention; Detailed Implementation Manner
[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Please refer to Figure 1 ,
[0033] Embodiment:
[0034] I. Implementation Preparation
[0035] Install required software and tools: Before performing solid-state drive data recovery, ensure that software and hardware such as File System Monitor (file monitoring tool), Extension Analyzer (file extension identification tool), HDTune Pro (hardware scanning tool), Victoria (professional hardware scanning tool), Flash Utility (firmware repair tool), Chip Data Recovery (chip data recovery software), interface conversion device, GetDataBack Pro (professional data recovery software), Data Validation Toolkit (data verification tool), Partition Wizard (partition management tool), etc. are installed on the computer. At the same time, prepare the development environment and tools required for developing an automated monitoring and recovery system.
[0036] Prepare storage media: Prepare other hard disks (such as mechanical hard disks), USB flash drives or ensure a stable network connection to use cloud storage services (such as Baidu Netdisk, etc.) as the location for establishing a secure partition. At the same time, prepare secure storage media such as external hard drives and optical discs for copying the repaired data.
[0037] II. Specific Implementation Steps
[0038] Step 1: Monitoring and File Identification
[0039] Start the File System Monitor to record the storage space data and the number of files in the solid-state drive partitions when the system boots up and shuts down.
[0040] Use the Extension Analyzer to identify whether the files with changed file counts are cache-type files based on the file suffix names. For the identified cache files, according to the established processing method, clarify that their loss due to power-off does not need to be restored.
[0041] Step 2: Hardware Scan Trigger
[0042] When it is recognized that the number of files decreases and they are not cache-type files, immediately start HD Tune Pro for hardware scanning, no longer limited to the condition of manual file deletion, to more comprehensively detect possible faults. At the same time, the automated monitoring and recovery system starts to monitor the scanning process in real time and is ready to automatically execute subsequent steps when needed.
[0043] Step 3: Establish a Secure Partition and File Copy
[0044] If creating a secure partition on other hard drives (such as mechanical hard drives) or USB flash drives, the operating system's disk management tool or specific partition software can be directly used to create the partition and mark it as a secure partition.
[0045] If cloud data storage is selected under network connection, such as using cloud storage services like Baidu Netdisk, upload the undamaged files to the cloud storage.
[0046] Subsequently, copy the undamaged files in the solid-state drive to the secure partition to ensure the security of these files during the subsequent recovery process. The automated monitoring and recovery system can automatically record the copy progress and status.
[0047] Step 4: Hardware Scan and Fault Identification
[0048] Run Victoria to perform a professional hardware scan on the solid-state drive, carefully identify the fault types and locations, and provide a basis for subsequent precise repair. The intelligent fault diagnosis module starts to analyze the scan results and uses artificial intelligence and machine learning technologies to assist in more accurately identifying the fault types.
[0049] Step 5: Fault Repair
[0050] According to the results identified in step 4, adopt corresponding repair strategies to repair the faulty area. If it is a physical fault, such as an interface damage, an appropriate interface conversion device can be used for interface conversion; for circuit damage, ChipData Recovery can be considered for chip data recombination; for abnormal heating determined to be caused by circuit board deformation, circuit breakage or abnormal high temperature of the chipset, firmware repair (using Flash Utility), chip data recombination or physical replacement of damaged hardware components can be adopted respectively.
[0051] Step 6: Data Recovery
[0052] For firmware faults, such as the presence of bad blocks, read errors, module loss, logical bad sectors and parity errors, use the professional data recovery software R-Studio. Connect the faulty hard disk to the computer, start R-Studio to scan and identify the partitions on the hard disk, and select the data to be recovered for recovery. At the same time, the remote data recovery service platform can remotely assist in data recovery with the user's authorization.
[0053] Step 7: Deep Scan and Data Retrieval
[0054] Start GetDataBack Pro to perform a deep scan on the solid-state drive to retrieve the lost data as much as possible. The automated monitoring and recovery system can automatically optimize the scan parameters to improve the efficiency of data retrieval.
[0055] Step 8: Data Verification and Repair
[0056] Use the Data Validation Toolkit to verify and repair the retrieved data to ensure the integrity and accuracy of the data. Check whether the data is damaged, missing parts or incorrect, and perform corresponding repair operations. The intelligent fault diagnosis module can further optimize the repair strategy according to the verification results.
[0057] Step 9: Formatting and Partition Table Reconstruction
[0058] Use Partition Wizard to reformat the solid-state drive and reconstruct the partition table to prepare for storing the recovered data. The automated monitoring and recovery system can automatically monitor the process of formatting and partition table reconstruction to ensure a smooth completion.
[0059] Step 10: Data Copying and Storage
[0060] Copy the repaired data to a secure storage medium, such as a portable hard drive, optical disc, etc., to ensure the long-term secure storage of the data. The automated monitoring and recovery system can automatically record the copy progress and results and send a notification after completion.
[0061] III. Continuous Optimization and Expansion
[0062] Continuously update the intelligent fault diagnosis module: By analyzing more fault cases and data, continuously train and optimize the intelligent fault diagnosis module to improve its accuracy and adaptability.
[0063] Improve the remote data recovery service platform: Add more functions and services, such as real-time communication, remote operation guidance, etc., to improve the efficiency of remote data recovery and the user experience.
[0064] Strengthen the health monitoring and warning of solid-state drives: Continuously monitor the health status of solid-state drives, such as indicators like temperature, read / write speed, remaining life, etc. When abnormal situations are detected, issue early warnings so that users have enough time to take measures, such as backing up data or performing preventive maintenance, to avoid data loss. At the same time, the automated monitoring and recovery system can automatically start the backup or recovery process based on the health monitoring results.
