I plug my hard drive into my computer it always says scan and repair

Each time i plug my hard drive into my computer it always says scan and repair i used to ignore it then one day i thought let me do it so while doing it it was on the second day still scanning then i accidentally hit the cable and it stopped scanning i decided to start again but when i plug into the computer it just makes a clicking sound and the white light flashes it goes off for few seconds and back on and i also noticed it's stopped vibrating is this an issue? i can see it appear in the computer but files cant be accessed. please help if you can thanks
