- Is my HDD on the verge of failing? 3 answers
About a week ago my Windows 7 PC got progressively slower over a day or two before it got the point where it was unusable. Everything would pretty much freeze when trying to even carry out the most mundane of tasks (i.e browsing the web). When I attempted to run a virus scan, I noticed the read/write speeds were really slow, and the same when I was deleting/transferring files on the hide drive.
I subsequently thought there may be a hard drive problem, but nonetheless I tried a clean OS install, and everything worked fine. A few days later, suddenly everything locked up on me again. At one point it failed to boot, launching the windows boot recovery (I can't remember the exact name - launched because windows failed to start up), which itself couldn't start, showing me a black & white screen saying that the hard disk may be failing.
I've since run an Ubuntu live CD and run a SMART scan on the hard drive, but I'm not sure how to digest the results (see below). There's a tonne of stuff about Pre-fail and Old_age so I would assume it's time to buy a new hard drive, but I'd be really appreciative if someone could tell me exactly what this info means and whether or not I'm correct.
