so, i've read heaps of help pages and none have worked so far, my Western Digital 3TBHD isn't being opened by my computer, it appears in disc manager and i can safely remove it and i only got it a month ago, ive moved about 300 gigs or less on to it, ive tried to change the disc letter but administrative tools said it wasn't available or ready, i ran WD Lifeguard Diagnostics and it stopped scanning after a second and said too many bad sectors, what the hell? i only had it a month, how do i fix this?
