What is the bad sectors?

Bad Sectors

Before removing bad sectors from hard drive, let us first understand what is the bad sector?

As the name suggests, bad sectors are inaccessible or unwritable sectors on a hard drive or flash drive. This is usually due to physical damage to the surface of the disk or failure of the flash transistors. In addition to the quality problems of the hard disk or flash disk itself, natural aging and improper use will also cause damage to the hard disk or flash disk. If your hard drive has bad sectors, you may not be able to access the data on it. What's more, data on the hard drive may be lost. Therefore, it is necessary to clear the bad sectors of the hard disk!

How to eliminate bad sectors on hard drive

It's okay if you don't know how to remove bad sectors, here show you two free methods of how to remove bad sectors from hard disk permanently. Including Windows built-in utility and third-party hard disk bad sector repair software.

Method 1. Remove bad sectors from hard disk via CMD

CHKDKS command prompt is a free Windows built-in tool, and it can be used to check the integrity of a file system and bad sectors of a disk. And find and fix bad sectors, errors, or any other disk problems. Here are the specific steps of removing bad sectors from the hard disk via CMD:

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

2. Input “chkdsk g: /f /r /x” and press “Enter”. (Here, “g” is the drive letter of the disk you want to check.)


This option will run the CHKDSK to check and repair bad sectors or other disk errors on G: volume. The “/f” parameter tells CHKDSK to fix any errors it finds, “/r” tells it to locate the bad sectors on the drive and recover readable information, and “/x” forces the drive to dismount before the process starts.

And now you can see the information of the disk such as disk space parameters, file size, and the number of bad sectors.
