Passport is not getting detected :(

my passport essential of 1TB is not getting had been used many a times before.its not suddenly not working.its LED is glowing when i connect it to my laptop but the drive is nt being shown.please help me out 

Connect it to a linux and Perhaps it works. It happaned to me before; my disk could not be deteced on my laptop. Linux detected it, and after two days, the linux also could not detect it.

But it was fixed automatically after a week or so. It got detected easily. You may do the same.
