Hard disk integer partition calculator.

A hard disk integer partition calculator is a tool used to determine the number of partitions that can be created on a hard disk based on its size. It calculates the maximum number of partitions that can be created using the traditional Master Boot Record (MBR) partitioning scheme, which supports up to four primary partitions or three primary partitions and an extended partition containing logical partitions within it. The calculator takes into account the disk size, sector size, and cluster size to determine the maximum number of partitions that can be created. This information can be useful for users who need to partition their hard disk for different operating systems, data storage, or backup purposes.
