Windows defender custom scan does not scan external drives

I have Defender Windows 10. I tried using custom scan to select and scan external drives. The screen listing the drives comes up, but the "OK" button remains grayed out so unable to scan any of the drives listed. Any suggestions would be appreciated.

 

Error: problem with this drive. Scan the drive now and fix it when connecting an HD drive

Hi,



Thank you for writing to Microsoft Community Forums.



To get a clear picture of the issue, we will need the following details:

• When exactly are you receiving the error message?
  
• Have you tried connecting the drive to any other USB port?
  
• Are you able to access the drive on any other computer?
  
• What is the make and model of the computer and the HD drive?
  

In the meantime, I suggest you to refer the troubleshooting steps mentioned below:



You can scan the drive for errors by following the steps mentioned below and see if that helps:

1. Press Windows key + E, to open
   File Explorer.
   
2. Click on This PC on the left pane.
   
3. Right click on the HD Drive and select
   Properties.
   
4. Click on Tools tab, under
   Error Checking click on Check. This will scan the drive for error and fix them.
   

Note: If any bad sectors are found on the hard drive while Windows try to repair the sectors, data on the sectors might be lost.



Please reply with the status of the issue, we will be glad to help you further.
