How to Check & Fix Bad Sectors on the Hard Drive

Apr 21, 2023

Sectors on a hard drive are sections of the platter where data is written and read from. Think of them as a small container within a much larger one. Is this much easier to understand? Over time, sectors may be damaged.

When the OS is unable to read data from a sector, unluckily, this sector becomes a bad sector. Bad sectors refer to permanently damaged disk sectors which come in two different types: hard & soft. Neither of them is usable, but will easily destroy the drive and any data within them. The files in bad sectors may become corrupt. What’s more, bad sectors can even cause 100% disk usage issue.

Bad sectors on disks are fairly common, however, the Windows built-in disk check tool can find and fix bad sectors. Please follow the steps below.

Step 1. Open File Explorer
