Question Seagate Plus External Hard Drive 4TB Not Turning On All Of A Sudden

[Pawpaws]

.. An external hard drive i had just reformatted all of a sudden isnt turning on, No matter which computer or port i plug it into. It has really important information on it, What do i do.
None of my USB-sticks ever had this problem, But now this thing acts this way. The light wont turn on, It doesnt need an extra power source but i dont hear the motor turn on.
I dont know who to turn to or what to do about it.

I was feeling so good, Because jd finally got this thing working again. And now THIS happens. >.<

It also worked FINE once reformatted, And i began putting my hard-won data like movies back onto it. Sigh

You could try tapping it LIGHTLY on the floor once or twice. NOT TOO HARD OR YOU WILL DAMAGE THE RECORDING HEADS. I have had Seagate drive spindles stick due to dirt. I have used the above to bring them back long enough to get data off if them. But sounds toasted...also some larger drives have a sector with drive data for the BIOS, and a format could wipe that sector.
