Turning a harddrive off (suddenly, which i don't even think is the case here) can mess up a file system. But in this case there isn't even a file system to mess up.
And there is absolutely no harm done to a modern harddrive that has its power cut off suddenly.
Thanks for the reply. Anyways I turned it off...That first reply scared me, lol. But it seems generally that it'll be ok, right? I just need to start the process again. Its a brand new western digital caviar black so there's no data on it.
