Quick Partition

This function is used to repartition hard drive quickly. And this function applies to partitioning new hard drives or completely repartitioning a hard drive that already has been partitioned. PartitionGuru will delete all existing partitions and partition hard drive in line with requirements; then it'll format all partitions. User can set partition's size, type, volume label, etc. Just several steps are enough to partition and format. If you don't change the defaulted settings about partition number, type, size and so on, you can click "OK" (shortcut key F6) directly to finish the repartition.

To start quick partition, select a hard drive, and then click Quick Partition"or just click the key F6. PartitionGuru will show the following dialog box:

Quick Partition Dialog

By default, PartitionGuru takes the current hard drive as the target hard drive to partition. If the current disk isn't the one you want to partition, please click disk's name on the top left,and PartitionGuru will pop up the dialog box for selecting disk.

1.Specify partition count:

You can press "3, 4, 5 or 6" to select partition number, or you can also just click mouse to select the partition number. The right part of the dialog box shows the partition list.
The default partition number is determined by disk capacity, as shown below:

Size of disk Default partition count
less than 60GB 3 partitions
60GB - 150GB 4 partitions
150GB - 320GB 5 partitions
 320GB + 6 partitions

2.Modify partition parameters:

The right half of the dialog box shows partition's type, size, volume label and whether the partition is primary partition. Users can modify these parameters according to their needs.

a.Partition Type:
The quick partition only provides two types: NTFS and FAT32.

b.Partition Size:
The default partition size is calculated by following rules: First, according to the partition number, if every partition is smaller than 15G, PartitionGuru will split the disk by average. Second, if the average size of each partition is no less than 15GB, then first partition is assigned 1/20 of the totally capacity. 25GB is the minimum size and if the calculated size is smaller than 25 GB then the first partition will be fixed as 25GB. Other partitions divide the rest space by average. This is considered that the partition is usually used to install operating system and software; if it's too small then it can't install so much software and it'll be a waste of space if it is too large.

There is an icon looked like a "lock" on the left of the edit box for inputting partition size. When the user changes one partition's size, then this partition will be "locked" so that its size won't be changed automatically when other partitions are adjusted. User can change the "lock" state by clicking the icon; when initialized or partition number is changed, the first partition is locked and other partitions are unlocked; if one partition's size is changed, other unlocked partitions will divide the rest space by average automatically; if all the partition are locked except the partition being changed, PartitionGuru will just adjust the first and the last partitions' size. If the final adjusted partition is the first partition, PartitionGuru will automatically adjust the last partition, and vice versa. Partitions that have been adjusted will be unlocked automatically.

Click the button "Default Size" and PartitionGuru will reset partitions' size according to default rules.

Partitions created by this function are "Integral Size Partition" except one partition that uses the remaining space of the disk. The size of an "Integral Size Partition" shows in integral size in Windows Explore, which looks more beautiful, as follows:

Integral Size Partition:

Non-integral Size Partition:

c.Volume Label
PartitionGuru assigns a default label for every partition, but users can change it or select one for it. Also users can click the button "Clear All Labels" to delete all labels.

d.Primary Partition or Not(This option is invalid for GUID partition table)
It is allowed to choose one partition as primary partition or logical partition. You should note that there are at most 4 primary partitions in a disk, and if there are more than 4 primary partitions, the extra partitions should be assigned as logical partition. Extended partition is primary partition too. PartitiomGuru will automatically adjust whether this option can be checked or not.

e.Align Partitions
Some hard drives such as Western Digital's Advanced Format hard drive with 4KB size physical sectors should align to integral multiple of sectors so that they can provide full performance. So you should check the option "Align Partition to Integral Multiple of Sectors" and select a required number for aligning.

3. Other settings:

a.Rebuild the Master Boot Record (MBR)
This is a default option. If there is a MBR based on booting manager program installed on the disk, and it must be kept for later use, please don't check this option.

b.GPT Disk:
This function also applies to building GUID partition table on GPT disk. On the right top of the dialog box, beside "Advanced Options", shows the partition table style ("MBR" or "GUID") of the current disk.

In addition to, for GPT disk, you can also choose the option of the ESP and MSR partition. If the ESP has already existed, you can choose "Keep the Existing ESP Partition" or "Create New ESP Partition".

After all settings are adjusted, click "OK" to start partitioning and formatting. If there are old partitions on the disk, PartitionGuru will show the following message box:

Dialog of warning message

After PartitionGuru executes quick partition, all the original partitions, if any, will be deleted automatically. And the primary partition built first will be activated automatically.
