Essential, slow 2 be recognized by Mac then beachball

Hello out there!

I have had this Essential EXT HD for over a year with intermittent problems like not recognizing the EXT HD etc. This time however, when It does recognize the EXT HD it is very slow to bring up any files and then when I double click on files it just goes to beachball and after a few minutes it will load the file but beachball preceeds every click for an action. Oh and lights are blinking constantly. I ran disk verify and disk repair with no faults found, ran power adapter directly to the wall, no surge protector and tried on another Macbook laptop with same results…help please!

You can defragment the hard drive and run data lifeguard diagnostics…
