Re: Is something horrible......
You should probably back up anything you don't want to lose on that drive... I have heard that noise before, a week or so later, it wouldn't spin up. No huge loss for me, as it was just a scratch/torrent drive.
Could also be a fan bearing going bad, but usually those noises are more constant.
