Ok so the last week or so, i have noticed some noises coming from my HD. It clicks once and a while, causing a second of lag. I Know clicking is not a good thing when it come to HDs. But the S.M.A.R.T. utilites say the fitness is 100% as is the performance. My question is how long do i have? And what should i do to back up? No i have no RAID setup available. WHat about an external drive? or should i just the thing drive? The PC is really only used for gaming, no professional stuff.
