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 recommended free tool 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 S.M.A.R.T attributes and change some HDD parameters such as AAM, APM, etc.

Step 1: Connect the mobile hard disk to the computer, press (Windows icon + R key), enter (diskmgmt.msc) in the pop-up input box, and then click (OK set) to enter Disk Management.

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. If you use 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.
