Windows 10: Defragmenting drive

So I opened the defragmenting app but it says my drives cannot be optimized, does anyone know why the drive cannot be optimized?

Defragment and Optimize Drives Problem

Hi Edward,

Based on the details you have provided, your C drive was unrecognized by the system. We suggest that you run these
commands and see if there are any changes:

• 
  Open
  Command Prompt
  as
  Administrator.
  
• 
  Run
  the following commands:
  
  • 
    To fix any logical file errors:
    
    • 
      Chkdsk C: /f /r
      
      
  • 
    To defrag your Drive C manually:
    
    • 
      Defrag C: /D /U
      

Update us on how it goes.

Regards.

 

Windows Defrag

When running defrag, there is a drive listing for Windows RE Tools. It shows as a solid state drive and that it has never been defragged. It will not optimize. Clicking on it does nothing. Any suggestions?

 

defragment an external drive.

I have a drive that lists as a portable drive in computer management. It does not show up on list when I try to defrag it. I believe it is because it's listed as a portable device. How can I get it to defrag without losing all the data on the drive?
