Affiliate Marketing Secrets

My acer laptop computer, with a WD Caviar Blue harddrive is stalling randomly for no reason.
Whiler windows is doing it’s “per-second-hdd-short-access” thing, the harddrive kept on parking and unparking it’s head and at times its parking took more than 2 seconds and windows hangs (i mean mouse cant even move) and resumes after that. And while im typing this, it stalls again and is very annoying.
Should I worry about the harrdrive failing? The harrdrive doesn’t seem to be failing at all, SMART data says ok to everything, and not a click-of-death was heard, except for the stupid parking and unparking mechanism.
