This guide describes a simple way to check, repair and remove bad sectors for the USB drive using Windows drive error checking tool. A bad sector is an area on a USB flash drive that cannot be accessed, written or read, and therefore cannot be used. There are two different types of bad sectors: hard and soft.
Hard bad sectors are caused by physical damage. Such as the quality of the hard disk or the flash drive itself, natural aging and non-standard use can also cause damage to the hard disk or flash drive, the bad sectors of the hard disk cannot be repaired. But with some knowledge and common sense, they can be prevented.
Soft bad sectors are logical problems. Soft bad sectors can occur due to software or data errors. Soft bad sectors can be fixed by completely erasing the drive or by using the CHKDSK utility in Windows operating system.
