How to Merge C Drive with D Drive in Windows Server?
Want to merge C drive and D drive in Windows Server 2019/2016/2012(R2)/2008 (R2)/2003 without losing data? Refer to this post to get detailed steps.
“I have a problem that my system partition that with Windows Server 2012 installed is too small to install more software, while the D drive has a lot of free space that can be used to
merge these two partitions together to increase the capacity of C drive?”
Because Windows disk management does not support to merge partition C with partition D directly, the only solution to this issue is that you have to delete partition D, making it an unallocated space, and then you can merge this unallocated space into C drive.
Warning: To delete partition D means you will lose all your data in it unless you make a backup or move the data to another location.
Step 1. Press Windows + R simultaneously, input diskmgmt.msc and click OK.
Step 2. Right-click D drive, choose Delete Volume and click Yes to confirm.
Step 3. Right-click C drive and choose Extend Volume.
Step 4. Follow the prompts to complete the operation.
To combine C drive with D drive without deleting partition, you can turn to a third-party partition manager software for Windows Server, AOMEI Partition Assistant Server. It is compatible with Windows Server 2019/2016/2012 (R2)/2008(R2)/2003 and Windows 10/8.1/8/7, XP and Vista. After merging, you can see an enlarged C drive and a folder named D drive, which contains all data saved in the previous D drive.
Note: To settle C drive full while D drive has plenty of space, you can also use the partition manager software’s Allocate Free Space to allocate free space from D drive to C drive rather than merge these two partitions.
Now, install and run AOMEI Partition Assistant Server on your machine and refer to steps on how it merges two partitions: C drive and D drive in Windows Server.
You can download its demo version to have a try!
Step 1. In the main interface, right-click C drive and choose Merge Partitions.
Step 2. Tick the tick adjacent partitions (merge unallocated partition is not in this limit) you want to operate. Here choose partition C and D. Click OK to continue.
Step 3. Then a preview of this operation comes out. To make it into effect, click Apply and Proceed at the top-left corner.
Only two partitions can be combined at one time and these two partitions must be contiguous while you can merge two or more unallocated space into a partition no matter the unallocated space is contiguous the partition.
The host partition needs to have at least 1GB free space before merging.
You can merge data partition into system boot partition, but you cannot merge system boot drive into data partition.
You can also use AOMEI Partition Assistant Server to settle other issues, such as partition is deleted accidentally, basic disk is converted to dynamic mistakenly, etc.
