Wd passport not recognised drive works on samsung tv

Watsup Guys, I tried, and researched and wasted over a week trying to fix this.

Eventually after installing ses drivers and what what, firmware updater doesnt work and I'm on this page now.

I have an ext hdd500gb, my passport, worked perfectly then I remember filling it worked well for a day or so after, and ever since just says windows does not recognise.

Laptop is an HP. All other devices connect.
Desktop is running Windows 7 as well.

Funny thing is when I connect it to the usb on my samsung tv, it works like a bomb.

Light comes on, hdd is spinning like a gem when connecting all the time. So its obviously not stuffed yet.

They killed the start up file but this is so frustrating now, wd couldve done better.

Guys please help.
I need a driver, I think it asked for *.inf file.

Thanks alot,
