We fixed this on a Vista laptop by replacing the default Intel "enhanced" disk controller driver with an older and more standard driver. Enhanced my ass, the speed increase was drastic.I'd agree with Vista I still blame that OS for killing two hard drives, I just could not stop it from constantly indexing, no matter what I did my computer would just sit and consistently read from the HDD even when idle with indexing off. And it ran very slowly especially considering I had pretty much a top end machine at the time of release.
