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.
Partition a hard drive has many meanings. It is important that you understand what you want. Given that you have already existing partitions on the hard drive and just want to resize some of the partitions or create a new partition to better manage files. Disk Management can help you achieve the goal. If you have unallocated space on the hard drive, you can partition a hard drive by creating a new volume. If you don’t have an unallocated space, generate one by shrinking one of the existing partitions. Steps are very simple.
Right click the “Computer” icon on the desktop and select “Manage”. Click “Disk Management” under “Storage”.
Right click the unallocated space and select “New Simple Volume”. Follow the wizard to complete creating. You can create a NTFS or FAT32 partition.
If you don’t have unallocated space on the hard drive, right click any redundant partition and select “Shrink Volume” to generate one. Then repeat above step to create a partition.
Supposing that you have an empty hard drive needs to be partitioned. You can utilize Diskpart in Windows Command Prompt to create several primary partitions or extended partitions.
Press “Windows + R” key to open Run box. Type “cmd” to open “Command Prompt”. Then input “diskpart” and hit Enter.
Type “list disk”.
Type “select disk 1”. Disk 1 stands for your empty hard drive.
Type one of these commands to create desire partition: “create partition primary [size=n] [offset=n] [ID=byte | GUID] [noerr]” or “create partition extended [size=n] [offset=n] [noerr]” or “create partition logical [size=n] [offset=n] [noerr]”.
Type “assign letter=H”. Then partition H would be the one you just created.
Tips: To create more partitions, please repeat above steps.
