Passport SE Stopped recognizing

I have a WD Passport SE for Mac HDD - Model no. WDBABW0010BSL

Last night I plugged it in to transfer some files and it worked fine, loaded my folders correctly but when I went to copy a few files, I got beach balled and it froze for awhile. To the point where I couldn’t do anything with it so I had to pull it out. Soon after I plugged it in and it was still running really slow but still working. Later that night I went to use it again and since then I have not being able to get it working, the HDD LED power light it works. But after a short time I hear a click then the activity light starts working…

Please Help!?
