Sector is the logical unit of file storage on a hard disk. Actually sector is a subdivision of a track on a hard disk, while track is a circular path on a disk that stores magnetic information. Each sector has a defined storage capability that is 4096 bytes (4KB) nowadays in latest disks; whereas older disks had cluster size of 512 bytes or 2048 bytes. In this post I'm going to tell you how to find the cluster size of your hard disk in Windows.
