Why Does It Stop Working?

The Disk Defragmenter tool rearranges files on your hard drive so that they are stored in a contiguous manner.

This helps to improve file access speed and overall system performance.

Disk fragmentation can occur over time as you add, remove, and modify files on your hard drive.

If not, move on to the next solution.

This tool will scan all of your system files and replace any that are corrupt or missing.

SFC and DISM Scan

Once the scan is complete, cycle your rig and try running Disk Defragmenter again.

It should now work properly.

However, you should let it complete its task uninterrupted.

Run chkdsk command

Close All Third-Party Applications

Some third-party applications may interfere with Disk Defragmenter if they are running.

In such a case, close all third-party programs and see if that helps the defragmenter to run properly.

As such, you could try ending some third-party processes and see if that fixes it.

Close Programs Via Task Manager

After closing one, see if the disk defragmenter works again.

If it does, the service you just closed is the culprit.

However, sometimes the Disk Defragmenter tool doesn’t work as expected.

in case you find this problem, the methods described above should help you resolve it.
