How do I run CHKDSK to fix bad sectors?
Check Disk (chkdsk) is a tool used to verify the integrity of the file system and is also used to find bad sectors on hard drives. It also helps in recovering corrupt data when a system failure occurs that affects the integrity of data (e.g. power failure).
Check Disk can examine FAT16, FAT32 and NTFS drives and automatically repair errors. Below are the steps in Windows 7, Windows 8 and Windows 10 to run chkdsk on your system.
Open Windows Explorer and right-click on the disk you want to check. At the bottom, click Properties.
