My wd hard drive not recognise on pc vista

Hi i went and format my hard drive and it has erase everything including the wd files that were on it. i dont need the files i erase but now the hard disk just come up on my pc as d drive and not as wd passport.

do i need the wd files i erase to work the hard disk? if so where and how will i download them back pls?

Reason i formatt it was cos it was not working properly. the files i download gets all jumble up after downloading and could not be read by the laptop.

Is my harddisk damage? pls help

If you only need to change the name, right click on the “d” drive and select the rename option.
