The error: There is not enough space on the disk
You may encounter an error “There is not enough space available on the disk(s) to complete this operation” while doing some operations such as create/shrink/extend/format partition, and convert to GPT disk or dynamic volume and so on using Disk Management in Windows 11/10/8/7. Well, what does this error mean?
Generally, this type of error can emerge while creating a new simple volume, shrinking partition, or converting to dynamic disk. Here, I’ll list them in the following one by one.
☞ "There is not enough space on the disk to complete this operation create partition."
This error occurs when you delete partition and get free space instead of unallocated space. In that case, you need to delete free space and create partition with unallocated space. Besides, you can create partition with a partition manager.
☞ "There is not enough space on the disk to complete this operation while shrinking partition."
If the volume you want to shrink containing unmovable files in the middle of the disk, you cannot shrink volume. Also, if there are page files or unmovable/locked system files at the end of drive, you will receive there is not enough space on the disk error.
☞ "There is not enough space on the disk to complete this operation convert to dynamic disk."
You can’t convert to dynamic disk if you do not have at least 1MB unallocated space at the end of disk which is used to create the database for the dynamic disk. This space is reserved when you create a partition or volume in Windows 2000 or XP Professional. But it does not work in other operating systems.
To fix the error, you need to shrink the last partition and create a space for database. Besides, you still use partition manager to directly convert basic disk to dynamic disk.
▪ "There is not enough space on the disk to complete this operation extend partition."
▪ "There is not enough space on the disk to complete this operation format partition."
▪ "There is not enough space on the disk to complete this operation delete partition."
▪ "There is not enough space when converting to GPT disk."
What does there is not enough space mean? In general, it means you have insufficient disk space for operations, the hard drive is almost full and Windows is unable to perform further actions. Then, what can you do to fix it?
Fix there is not enough space available on the disk effectively
In Disk Management, there are many limitations than you can expect. You cannot waste time on solving problems continuously. You are supposed to turn to some free third-party partition tools like AOMEI Partition Assistant Standard, helping you finish all the tasks in Disk Management and fix problems caused by Disk Management.
Note that errors that happen under different circumstances require different solutions.

To fix this error, you can delete free space and create partition with unallocated space.
Step 1. Press Win + R to summon the Run window, type diskmgmt.msc in the box and hit OK to open Disk Management.
Step 2. Right-click the free space, click Delete Volume, and then follow the wizard until the last step.
Step 3. Right-click the unallocated space, click New Simple Volume, and then follow the wizard to finish the rest of the steps.

If you receive not enough space error while shrinking, you can try Rescan disks to reload disks and see if it works.

▶ Try disk defragmenter to free up disk space
Sometimes, fragment pieces at the end of volume may cause this problem. You can run disk defragmenter to fix it. Note that it is not suggested to perform disk defragmenter on SSD disks.
Step 1. Type disk defragmenter in the search box and select it from the searching result.
Step 2. Choose disk you want to defragment section, click Analyze disk button, and check fragment percentage. If the percentage exceeds 10%, you should run the defragment.
