it was working fine this morning, and i'd left my computer copying files on to it all day, and when i got back to it just now it started telling me that this hard drive doesn't exist.. it had it as g:, and i have another one plugged in now called f: (which is showing up okay), and my computer's hard drive is split in two, c and d, so it's not a name confusion thing.. just stopped working all of a sudden, even its little light isn't lighting up.. .. i managed to use it fine once before, to copy files on to (needed to do that so i didn't lose everything when i wiped my computer's hd, for another reason (most stubborn virus i've ever met)).. .. so what should i do now? is my stuff still salvagable?
