sudden large deterioration in hard drive performance

Up until a few days ago, drive performance was massively better than seen below.

System is as seen in sig; severe performance loss in drive access, opening folders is very slow. Programs, games etc still work apart from when the high CPU usage as seen in the screenshot cripples the system, which has been as stable as a rock for nearly 3 years. System is less than 0.2% fragmented and regularly maintained. There are no unusual noises as yet. No drastic system changes of late either.

Is this the start of drive failure or is this something thats gone wrong in the OS?

Luckily I have a new build under construction and the important stuff on this drive is backed up, but it's hugely annoying.

Try running "Chkdsk /F C:" in cmd. Hit Y to have it check next reboot. Then give it a restart .

I'd definitely run a virus scan. Everytime I've experienced issues with slow folder opening, it's always pointed me to a virus.

If it isn't a virus, then I'd suggest running a SMART self-test on the drive. Unfortunately HD Tune doesn't seem to have any way to do this. The only Windows utility I was able to find which is capable of doing this is DriveSitter.

See also the link in my sig.
You're most likely, for some reason, developing a large number of bad sectors on the drive. More than normal, and more than can be recovered through normal drive self-check/self-recover means.

I'd personally probably back up everything on that drive to a new drive, and then do a low-level format against the Hitachi, along with a bunch of other manufacturer-specific tests to check for issues. Look for the Hitachi Drive Fitness Test utility to use. I'd give you a link right now but I'm posting from an iphone...
