go to my computer, to find the drive letter of the hard drive. ie drive (E)

go to start, run, and type in cmd

a black DOS screen will appear.

from here you enter

format "format e:" with out the " 's

it will say all data on this drive will be lost

do you wish to continue Y or N

hit Y, and the drive will be formatted.

Once complete it will ask for a drive name or press enter to continue.
