When I insert the U disk and mobile hard disk , the desktop does not show the external disk logo , and I also highlight the finder's external disk in terms of general and sidebar , but no one would show it .

I go to the disk utility ,it shows no monuted , but before that , I can directly open them and operate the disks .  When I press Mount , it says Try running First Aid on the disk and then retry mounting. . I try verify and repair , it does not work neither .
