External hard disk wont be seen by pc but is still running please help

Hi i cant make up out of this categoriesation if im right here but here is my problem.

I have a external hard disk a Western Digital Elements 2TB USB 2.0 Desktop External HDD And i have all my files on there.

A couple of days ago i thought it would be wise to take the files off and put them in a new hard disk sinc i bought this one like 4 - 5 years ago.

Durring the extraction the disk got a little tap on the housing from a low fall on the ground but now i cant get my pc to regonize it anymore not even when i take out the hard disk an connect it directly in the pc.

Usually the white led on the front only starts to blink when its connected and stops when it disconnects but after the fall it still doesnt blink until its connected but when i disconnect the usb cable the led stil keeps on blinking.

Its possible because it has a external power source but it shouldnt be doing that.

But when its connected i can hear the harddisk run and i cant hear a ticking sound.

Is there anyone who can shine some light on the matter?
