When it comes to GPT disk, you may ask what GPT is. GPT is short for GUID Partition Table which is a partition type. And it is a part of the Unified Extensible Firmware Interface specification, and it is used to replace master boot record (MBR) partition table which uses 32 bits in BIOS system to store the logical block address and size information. As of 2010, most operating systems support GPT, thereinto, Mac OS X system only support booting GPT partitions with EFI firmware.
Compared to MBR, GPT disk break the limitation of MBR disk capacity and can support hard drive larger than 2TB – up to 18EB disk capacity. In addition, in partition number, GPT disk can be used to create up to 128 partitions whereas MBR supports at most four primary partitions or three primary partitions plus one extended partition. Moreover, the legacy BIOS only supports computer booting from MBR, but UEFI supports GPT and MBR. In GPT disk, there is a backup of partition table at the end of disk to recover data in system when there is a data error.
Consequently, GPT disk is used widely to store large data in computers because of its merits. If your system is Windows 8, you may need to partition GPT disk during the process of using GPT disks. But how to manage your partitions and disk? Is there any way to do this?
As you know, Windows has a built-in partition and disk management tool which is called Disk Management. You can use it to create volume, extend volume and shrink volume on GPT disk.
When Using a New Disk on Computer
When using computer, you may choose a new disk to store data, but the new hard drive can’t be used to do any operation until you initialize it to GPT or MBR. Here choose GPT disk for data storage.
Then you can create GPT partition in Windows 8. Just right click the unallocated space and select “New Simple Volume” to create simple volume with Disk Management.
Shrink and Extend Volume on GPT Disk
After a period of time, there will be a large amount of data saved to your GPT disk which may cause low disk space. In such a case, you can use it to resize GPT partition. However, Disk Management can’t extend partition on GPT disk when there is no unallocated space.
Note: If there is some unallocated space but it is not at the adjacent right side of the target partition, Disk Management will ask you to convert the selected GPT disk to dynamic disk.
In GPT disk, Disk Management is not powerful to resize partition in Windows 8, and it requires you to convert to dynamic disk which make you inconvenient to manage your hard drive. Therefore, to make up for the deficiency of Disk Management, MiniTool Partition Wizard is recommended to you. As a professional partition manager, it can be used to do GPT partition management and help you solve “how to partition GPT disk Windows 8” problem. Firstly you need to download this freeware and then do some partition operations.
If there is some unallocated space, you can right click it and select “Create” to create a new partition in GPT. During the process of creating GPT partition, you can select the file system, set the drive letter and set the partition size.
When your disk is running out of space, you can use this partition and disk management software to resize partition size in Windows 8 on GPT. Do as the following steps:
Case 1: when there is unallocated space
Step 1: Right click the target partition and select “Move/Resize”.
Step 2: If the unallocated space is adjacent to the target partition, you can move the slider to occupy the unallocated space to extend GPT partition.
Note: If the unallocated space is not adjacent to your target partition, you can use this tool to move it to be next to your target partition and then start to resize partition.
Step 3: You need to click “Apply” to perform all operations.
Case 2: when there is no unallocated space
In addition, if there is no unallocated space, you can use MiniTool Partition Wizard to extend partition to solve low disk space issue. Right click the target partition and select “Extend” feature. And then you can take some free space from other partition to increase partition size.
This freeware is really powerful to solve “how to partition GPT disk Windows 8” problem. Just try it at once. Download now.
