When referring to a computer hard drive, a disk partition or partition is a segment of the hard drive that is separated from other portions of the hard drive. Partitions help enable users to divide a computer hard drive into different drives or into different portions for multiple operating systems to run on the same drive.
With older file allocation tables, such as FAT16, creating smaller partitions allows a computer hard drive to run more efficiently and save more disk space. However, with new file allocation tables, such as FAT32, this is no longer the case.
- Information about creating partitions and setting up a drive in Windows 2000, XP, and above.
- Information about creating, deleting (unpartition), or otherwise using fdisk to manipulate partitions can be found on our fdisk page.
- If you wish to extend a partition, shrink a partition, combine partitions, or otherwise manipulate a partition that can be done through a standard partition program, we would recommend you look into Partition Magic.
In addition to the utilities to create hard drive partitions, there are hundreds of different partition types. Below is a listing of some of these partitions and a brief description about them. While all of these partitions are available, they will all not available in your partition utility.
