What happens when the disk has bad sectors?

When the hard disk is used for a long time, various problems may occur, and the “bad sector” of the hard disk is the most common problem among them. As the name suggests, a bad sector is a sector, that appears to be defective on a hard drive. It is inaccessible or un-writeable due to physical damage to the disk surface or failed flash memory transistors.

 The usual non-standard use (ex: the memory is too small for the application software frequent accesses and reads & write to the hard disk, fragmenting hard disk too frequently, inappropriate overclocking, low-quality power supply, dust entering, etc.) can cause damage to the hard disk. If the hard disk has bad sectors, the data on the hard disk may be lost. Therefore, you need to repair bad sectors in Windows 11/10/8/7, and back up important data in time to avoid data loss.

How to repair bad sector in Windows 11/10/8/7?

To repair bad sectors, the following guide provides you two methods to do this operation.

Method 1. Employ CMD to repair bad sector

You can perform a preliminary check at first by Windows built-in tool – CheckDisk. CHKDSK can be used to check the integrity of a file system and bad sectors of a disk. CHKDSK also recovers the file system and the logical & physical errors of the hard disk. Let’s see the specific steps of checking disk:

1. Press “Windows” + “R” to open the Run box, typing “cmd” and press “Enter”.

2. Input “chkdsk g: /f” and press “Enter”. This will check and fix errors that it found on G: volume. (Here “g” is the drive letter of the disk you want to check.)
