About Creating Partition
To create partition is actually to partition hard drive. Only after you creating partition(s) on a disk can you make use of the disk to save all kinds of data. All physical parameter of a disk are set when you create partition(s) on it, including MBR (Main Boot Record) and the destination for storing boot record backup. For other information later needed for the management of file system and other operating systems, it will be achieved by later advanced format.What are the advantages of creating partitions? Generally speaking, creating more than one partition enables you to have operating system separate from data, deploy multi-boot setups, and keep frequently used programs and data near each other. Therefore, you can manage your computer with ease. If there is only one partition (namely C drive) on disk:
When recovering the system, the whole c disk (the system disk) will be formatted. If all data are saved in c disk, they will all be wiped and cannot be restored.
Too many other things in system disk will slow down system running.
If there are several partitions and each partition stores different kinds of data, it is convenient for user to manage them.
After partition creation, the size of cluster will decrease, which improve the efficiency of data storage. (Cluster is the distributive minimum disk space to save files. According to the stipulation of operating system, a cluster can only be used to store one file. Therefore, the space occupied by files can only be integer times of the size of a cluster. However, if the size of a file is smaller than that of a cluster, the extra space in the cluster will be wasted. Thus, generally speaking, a small cluster is better)
Consider all the reasons above, it is necessary to create more than one partition on a hard disk.
Before You Do
For MBR disk, please check how many partitions there are already on hard drive? Because MBR disk only supports creating up to 4 primary partitions or 3 primary partitions and 1 extended partition which may include one or more logical partitions. If the number of partitions reaches the upper limit, please visit how to convert to logical partition to change one primary partition to logical one and then you can create partition(s) on it. For GPT disk, you can create partitions without limitation. And you can have more primary partitions. However, the Windows implementation restricts this to 128 partitions.
How To Create Partition?
AOMEI Partition Assistant provides two ways to create partition, please choose the one which is more convenient for you.
Tips: No matter which way you choose, please download AOMEI Partition Assistant in order to follow the guide.
Solution 1: Create partition with unallocated space
Step 1: Install and launch AOMEI Partition Assistant. Right click the unallocated space and select "Create Partition" in the left panel (if there is no unallocated space, please go to Solution 2).
Step 2: In the pop-up window, click "Advanced" to specify the information for the new partition, including partition size, partition label, drive letter, files system (NTFS or FAT), and partition type (logical or primary). You could also specify the size of the new partition by dragging the both edges. When all settings are completed, click "OK" to continue.
Step 3: Now you can preview the new created partition. Click "Apply" on the toolbar to commit the "Pending Operations".
We suggest you set the file system as NTFS.
If you set the drive letter as "None", the partition will be hidden, in other words, you cannot view it in "My Computer".
Solution 2: Create partition without unallocated space (within existing partition)
If there's no unallocated space, AOMEI Partition Assistant also supports making partition from an existing partition (this way will reduce the size of the existing partition).
Step 1: Install and launch AOMEI Partition Assistant. Right click the partition on which you are going to create new partition and select “Create Partition” in the drop-down menu.
Step 2: In the pop-up window, click "Advanced" to specify the information for the new partition, including partition size, partition label, drive letter, files system (NTFS or FAT), and partition type (logical or primary). You could also specify the size of the new partition by dragging the edge circle rightwards or leftwards. When all settings are completed, click "OK" to continue.
Step 3: You can preview the new created partition. To save the changes, please click "Apply" on the toolbar.
If you create partitions on SSD (Solid State Drive), we suggest you should tick the check box “Partition alignment for SSD” to align the partition(s) on SSD option.
If the disk where you want to create partition is MBR style and has already 4 primary partitions, you cannot create partition within system partition. In this case you can create partition within other data primary partitions, but the data primary partition you choose will be automatically converted to logical partition.
Solution 2 only available for Pro and higher versions, if you are using the Standard version, then it is not possible to create partitions on an existing partition.
