III. How to repair the failure of the mobile hard disk
1. Run antivirus software
Sometimes viruses and malware can cause hard drive failure. Therefore, scanning and removing viruses with antivirus software may fix some corrupted hard drives. It is recommended to connect the mobile hard disk to another Windows computer with antivirus software installed, and use reliable antivirus software to scan and remove viruses.
2. Use hard disk detection/repair software
If the hard disk has bad sectors, you can use special hard disk detection/repair software to detect and repair hard disk errors.
Step 1: Connect the mobile hard disk to the computer, download, install and run the hard disk bad sector detection tool on the computer, the free tool recommended here is: HDD-SCAN, it is a free software for hard disk drive diagnosis (also supports RAID array servers, flash USB and SSD drives). The program can test storage devices for errors (bad blocks and sectors), display SMART attributes and change some HDD parameters such as AAM, APM, etc.

Step 2: HDD-SCAN can output the scanning status to the interface in a graphical way. When the disk detects about 78%, there are a lot of bad sectors (B).
Step 3: HDD-Scan can also output scan logs, and the results are more detailed. After bad sectors are found, it is recommended to use the repair software provided by the hard disk brand to deal with them, such as SeaTools, Western Digital Data Lifeguard Diagnostic, etc. Please search the corresponding hard disk repair tools on the Internet according to the hard disk brand. Note: All data may be erased if repaired with repair software provided by the brand. If you don’t want to lose data, please back up your data first.
3. Use Windows built-in disk checking tool
You can try to use the Windows built-in Disk Check tool to check and fix external hard drive errors. Please do the following:
Step 1: Connect the mobile hard disk to the computer, press (Windows icon + R key) on the keyboard, please enter (diskmgmt.msc) in the pop-up input box, and then click (OK) to enter the disk management.
Step 2: In Disk Management, right-click on the failed hard disk partition and select (Properties) on the menu.
Step 3: In the (Tools) column, select (Inspect).
Step 4: If your system is Windows 7 or Windows 8, please check (Automatically repair file system errors) and (Scan and try to recover bad sectors), and Windows 10 automatically repairs all errors by default. Then wait for the inspection and repair to complete.
The disk check function is mainly to mark the space where bad sectors appear as unusable at the file system level, so as to prevent file data from being written into these unstable data storage spaces. After repairing, if you use hard disk detection software such as HDD-Scan to scan, these bad sectors will still be displayed. If you want to completely solve the problem of bad sectors, you can only perform
low-level formatting (not necessarily repairable) or replace the hard disk.
4. Run the chkdsk tool to repair hard disk errors
The chkdsk tool is a command for the Windows system to check the current state of the disk. It can display the disk state, memory state, and the number of discrete files in the specified path, and can also repair the disk. It is very simple to repair hard disk failure with the help of chkdsk tool. The specific operation steps are as follows:
Step 1: Connect the faulty hard disk to the computer, directly search (cmd) in the search box in the lower left corner, and select (run as administrator) to open the command prompt tool.
Step 2: In the opened command prompt window, enter the command ( chkdsk G: /f ) (G refers to the disk number of the hard disk), and press (Enter) to fix the error. After the repair process is complete, check to see if the problem is resolved.
Kind tips If (chkdsk G: /f) cannot solve the problem, you can also try (chkdsk G: /r), (/r) can find bad sectors and restore readable information, and (/r) includes (/f) feature and additional analysis of physical disk errors.
After using the above steps to repair the mobile hard disk, if you find that the data in the mobile hard disk is lost, you can use the following methods to restore the data.
