How to partition a hard drive in Windows 11 without losing data?
- Aug 14, 2025
I recently used Dr.Partition to partition my hard drive in Windows 11 without losing any data. It’s simple, reliable, and worked perfectly, but make sure to back up important files just in case before starting.

It’s easy for beginners too!
It's actually pretty easy to partition a hard drive in Windows 11 using the built-in Disk Management tool. I've done this before, splitting the C drive into two partitions to store files. All you have to do is right-click "This PC", select Manage, and then click Disk Management. Find the C drive, right-click and select Compress Volume, enter the amount of space you want to compress, and all that's left is to create a new partition. Remember to leave enough space for the C drive so that the system won't have any problems. The process was pretty smooth, but I would back up my data before doing it, just to be safe!
Specific steps:
- Open Disk Management (right-click "This PC" -> Manage -> Disk Management)
- Right-click the C drive and select Compress Volume
- Enter the amount of space you want to compress and create a new partition
- Note: Make sure to leave enough space for the C drive to avoid system problems.

This method does sound simple, using the Disk Management tool to partition hard drive in Windows 11. But I'm a little curious, how do I determine how much space to leave when compressing the C drive? Is there a recommended minimum amount of free space to avoid system problems? Also, if there is an error or failure during the compression process, will it affect the existing data on the C drive?
