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. 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.
run command prompt
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.
Enter the disk repair command
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.

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.
Run window input diskmgmt.msc
Step 2: In Disk Management, right-click on the failed hard disk partition and select (Properties) on the menu.
click properties
Step 3: In the (Tools) column, select (Inspect).
Toolbar selection check
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.
Tick Automatically fix file system errors and Scan for and attempt recovery of bad sectors
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.
