When we create a new partition in Disk Management, some parameters are set by default if we do not customize them, including the cluster size. Usually the cluster size is 8 (4096 sector). Cluster size is closely related to the read-write speed and the hard disk utilization. Small cluster size is suitable for small files to save disk space, and large cluster size is more reasonable for huge files to save responding time.

Thus, after a period time of usage, you may find that the cluster size needs change. Well then, how to change cluster size of FAT32 partition?
