My laptop isn't showing the external hard disk

I am using a Seagate exteal hard disk of 1TB. Unfortunately my laptop was out of power and got hibeated with the HDD coected to it. And I discoected the HDD before re-starting it.

And now my laptop's File Explorer isn't listing my hard disk when I coect it. I am using Windows10 on my Lenovo G50-70 laptop.

Please suggest any solution possible.

Thank you.
