Windows 10: Disk Defragmenter shows other drives not visible in "This PC"

Hi there. I would like to ask for anyone's thoughts. I've recently checked my Defragmenter. I'm using Windows 11 on a Dell Latitude 5400 Laptop. Would like to make sure my laptop is running well and does not have any virus. Upon checking "Advanced View" in my defragmenter, it showed 3 other drives that is not visible in "This PC".Here are snapshots.Recovery, and the 2 volume drives made me curious. Should I be worried? or Is there anyway I can remove this without resetting the laptop? Thank you for your answers!

Disk Defragmenter runs but when finished it now shows 14% fragmented.

Hi Jim,

Thank you for posting your query in Microsoft Community.

Provide us with the below details for better clarity on the issue.

• 
  Did you perform the defragmentation internally or on an external drive?
  
• 
  Do you face any performance related issues even after the defragmentation?
  

You can ignore the message if you are not facing any performance related issue
after the process is done. It might be due to some error in the reporting. Then it won’t be an issue to worry about. If that is not the case, and you are still facing performance related issues, I suggest you to try the below steps and check if it
helps.

Step 1: Run a Disc Check on the computer.

You can perform a check disk to spot any error in your hard disk. To do so, right- click on the start button>select command prompt (admin)> type “chkdsk” and press enter.

This will display the exact errors occurring in your hard drive. Restart the computer and try Step 2.

Step 2: Perform a Disk Cleanup on your computer.

Refer the link below for steps to perform a Disk Cleanup.

Now, Run Disk Defragmentation and check if the issue persists.

Hope this information helps and let us know the status of the issue we will be glad to help you further.

 

C drive not shown in disk defragmenter, but seen in disk management

Good day Dan!

As I had tried before, chkdsk did not work for at least 10 times, my C drive is still not visible in the disk defragmenter. I was not sure when this problem occurred but I suppose it was around 2 weeks ago.

It is possible that Disk Defragmenter service has been disabled or not properly running on your PC, causing defragmentation issues. To troubleshoot this, kindly try these following methods:
