Reasons to partition a hard drive

Partition, an independent part of disk, is used to do some specific aims. As we all know, many computer users create new volumes to store their personal information, for example, partition a hard drive for backups. Generally speaking, there are two volumes in the disk: one for operating system applications, and the other for data and files. Based on personal's needs, the more various files and data to keep, the more volumes need to create. Why need to partition a disk? Here are several reasons:

  • When there is something wrong in one partition, the other will not be affected. Putting all the things in one volume will seem too disorganized and undertake a great risk, because when the system crashes or virus attacks, all the information in the disk will be lost.

  • For business workers, storing files and data with classification makes them work fluently and easily.

  • If there are some files or data need to encrypt, it will save a lot of time to lay them in single partition, rather than the whole disk. Meanwhile, the system partition cannot be encrypted.

  • Partition a hard drive for dual boot. With the desire of using dual boot or multiple boots, a series of volumes are necessary to put them apart in order to make them work.

  • Partition a hard drive after installing Windows 7. After installing an OS, the hard drive partition layout may become unreasonable.
