Just downloaded HDTune and apparently, my drive 'needs to be replaced' according to the health status. I downloaded it because my HDD was accessing like crazy (turned out the computer was performing a random virus scan which I didn't know about). I've also had WoW go a bit jerky on me a little bit and I know that's nothing to do with my other components so I suspected the hard drive. Anyone know what all these failed bits mean? The drive isn't even that old 
Thanks for help. I bought it May last year so it's still under the retailer warranty I think. Should I return it?
