MY own has a similar problem i dropped only once then it worked for several hours and know its not working in any computer the light blinks and the fans spins and i hear like 14 clicking sounds it doesn’t show up in device manager but it gets wram and the fan still spins i really need help because there it too much precious data on it

Dropping a drive once is all it takes to damage it beyond repair.  This is the reason you NEVER trust your precious data to just one device.  I had to learn this the hard way, same as you.  I now back up my most important data on at least three devices.  I even use DVD archiving for my critical documents and pictures.
