When system C drive is full, it can't be better if you can re-size partition without starting over, otherwise, you have to waste a long time to recreate partitions and restore from backup. But to many server administrators, it is not an easy task. Many people ask similar questions such as: will it cause data loss while resizing partitions, which tool is better to resize partition on Windows Server. This article introduces detailed step to resize server partition with both Windows native tools and third party software.
In Windows Server 2003, Disk Management can only do some basic operations such as create, delete, format partition and change drive letter. From Windows Server 2008, Disk Management has new Shrink and Extend Volume functions to help resize partition without losing data (in most cases). However, it can only shrink NTFS partition, or extend a NTFS partition by deleting its right contiguous volume. If you want to resize FAT32 partition, or extend partition by shrinking another one, Disk Management is useless.
Press Windows and R together on the keyboard, type diskmgmt.msc and press Enter, then Disk Management will be opened.
How to shrink a partition:
To extend system partition with Disk Management, your disk partition structure must meet the requirements:
Learn why cannot extend C drive by shrinking other volumes.
Some server administrators like to use command tool, diskpart is such kind of tool which has many commands to a disk or a partition.
The same with Disk Management, diskpart only support resizing NTFS partition. It cannot resize FAT32 partition or extend a NTFS partition by shrinking any other one. In addition, Diskpart doesn't display Unallocated space, it only show all single partitions in a list.
Press Windows and R on your keyboard, type diskpart and press Enter. In the command prompt window, type help shrink or help extend, you'll see the syntax and limitations.
It is much easier to resize server disk partition with software, you just need to drag and move on the disk map. Better than Windows native tools, 3rd-party software has more advantages such as:
There are many software in the market, the GUI and functions are all similar, but it doesn't mean any one can accomplish this task well.
There is system/partition damage and data loss risk when resizing volume with partitioning software, because all associated parameters of disk, volume and files must be modified correctly. Any software error or hardware issue could cause system boot failure, partition corruption and data loss.
Better than other tools, NIUBI Partition Editor is much safer and faster because of the advanced technologies:
Download NIUBI Partition Editor, you'll see all disks with partition structure and detailed information of each partition on the right, available operations to selected disk or partition are listed on the left and by right clicking.
Follow the steps in the video to resize partition on Windows Server 2003/2008/2012/2016/2019:
If you use hardware RAID such as RAID 0, 1, 5, 10, do not break the RAID array or do any operations in the RAID controller, just follow the steps above. If you run Windows server as virtual machine in VMware or Hyper-V, there's also no difference to resize virtual disk partition.
Besides resizing server partition, NIUBI Partition Editor helps do many other operations such as copy, convert, defrag, wipe, hide, merge partitions, scan bad sectors.
