Is basically the creation of the separate divisions of the hard disk. The directories and files can be stored in different categories once the disc is divided into different partitions. Although more control can be had by more partitions but beyond a certain degree it can become quite a mess to manage multiple partitions. The size of the partition should be carefully considered and changing the size is also influenced by the file system that is residing on a particular partition.

Users may have more than one more than operating systems on a single computer by the use of multi-booting setups. There can be different operating systems installed on different partitions of the same hard disc and the user can have a choice of booting into any operating system at power up and the users can have a choice of using any OS when the computer is powered on.

The corruptness of one partition does not affect by any means. The drive’s data will still be recoverable. There are less chances of a file system running on this partition becoming corrupt. It raises the System output if there are more efficient smaller file systems. There is a less time consumption of the smaller MTF on the smaller partition file system than a larger MTF on the partition of larger systems.

A hard disc may contain a single extended partition which is secondary to the primary partition each of them is sub-divided into logical drives different operating system’s assigned drives identifiers.

In order to create more space the hard disks are compressed at times. This was done by the earlier windows and MS-DOS, STACKER, Superstor, double space and drive space. This was done by creating a large file and then storing all the data on this file. Initially it was opened by the device drivers and assigned a separate letter. The original partition and the compressed drive had their letter swapped to avoid the confusion, so the compressed disk will be C and the area that often contains some system files is given a higher name.
