What is partition?

To divide memory or mass storage into isolated sections. In DOS systems, you can partition a disk, and each partition will behave like a separate disk drive. Partitioning is particularly useful if you run more than one operating system. For example, you might reserve one partition for Windows and another for UNIX.

In addition, partitioning on DOS and Windows machines can improve disk efficiency. This is because the FAT system used by these operating systems automatically assigns cluster size based on the disk size: the larger the disk, the larger the cluster. Unfortunately, large clusters can result in a wasted disk space, called slack space. There is an entire sector of the software industry devoted to building utilities that let you partition your hard disk, such as Fdisk, Partition Magic, EASEUS Partition Manager.

Explanation

Whether partition can be recognized by system or not depends on the partition table and boot sector of partition. If partition table or boot sector of partition is destroyed by virus or deleted accidentally, you will not see the partition you need. In fact, the partition is not actually lost.
